Print preview documents don't get DocAccessibles because this currently causes crashes and doesn't provide much value.
However, we still want to tell a11y clients something useful when a print preview document gets focus, rather than a11y focus just going nowhere.
Therefore, we allow a11y focus to land on the OuterDocAccessible (browser element) in this case.

This parses BigInt property names as if they were computed, which means we don't end up neeeding to atomize
them.
This does mean that BigInt property names take a slower path on construction, meaning that it is possible
to measure a slowdown on executing the construction of a huge literal with thousands of BigInt properties.
This patch adds one bit to ParseNode.h, but does not change the overall size of parse nodes, as it fits
into padding around pre-existing bitfields.

This was always a temporary hack because getting `zstandard` installed into the `objdir` `virtualenv`s was impossible. With the changes made in bug 1656993, this is possible now, so we can remove all this.

The intended behavior of `inherit-from-parent-environment` is that the packages from the parent Python environment are available to the sub-`virtualenv`. The implementation of that behavior thus far has been around "site directories", the idea being that custom (non-stdlib) packages are likely to be installed in the "site directory". The limitation of this approach is that there's no one location, in practice, where packages are installed, and it's hard to enumerate a static list of all those possible locations across all platforms.
This patch circumvents the issue by ignoring the "site directory" question entirely and just looking at `sys.path`. If we're inheriting from the parent environment when creating a `virtualenv`, we just ask the parent Python what its `sys.path` is and configure the `virtualenv`'s `sys.path` on startup.

`flake8`, `black`, and `pylint` are all installed in `virtualenv`s when running `mach lint`, so installing these packages globally on image setup isn't necessary.

This should not have any functional effects, but it maintains a useful invariant
that the stored field is never NotSpecified. NotSpecified should only be used
as a default value for function parameters, and converted to some other origin
when "at rest" in the field.

For all the other scroll-behavior-* tests, the "complex" behaviour is the "test"
and the "let's scroll these things to their intended destination" behaviour is
the "ref", as one would expect. Except for some reason in scroll-behavior-6, the
"ref" branch is the one doing all the tricky scrolling things and the other
branch has the simple intended outcomes. This patch inverts the branches so
that the test behaves more as expected.

We `normpath()` the `_root` path when we save it, but the input `path` to `get()` is not necessarily also normalized. Normalizing it prevents unnecessary test failures.

When migrating RestoreState to actors we didn't consider that the child actor
gets recreated at every navigation, as its lifetime is tied to the inner
window.
This means that restoring state in one step is not possible, as restoring the
history will trigger a navigation from `about:blank` to the restored page.
To achieve this, we split restoring in two steps and we keep the state on the
parent actor instead of the child.
We move the restoring logic to a newly added GeckoViewContent parent actor,
which is more readibly accessible from both geckoview.js and
GeckoViewContent.jsm.

This test begins to fail due to a `pip` installation issue after bug 1660351. It's already disabled on macOS (also due to what the comment says is a `pip` installation issue), so it's very possible the custom `requirements.txt` that this test installs is deficient in some way that surfaces in certain `virtualenv`s under certain circumstances. I can't diagnose the failure, but what I have seen is that bug 1659539 will fix that problem entirely with no extra intervention required, so we should be able to re-enable this for Linux (and maybe macOS as well?) when that patch lands.

I did notice this issue while investigating a test failure on
browser/components/contextualidentity/test/browser/browser_serviceworkers.js
The issue seems to be triggered when we are using a preallocated child process
for a call to RemoteWorkerManager::LaunchNewContentProcess, when that happens
we do expect that the new process is going to call RemoteWorkerManager::RegisterActor
once its RemoteWorkerService is being initialized in the new child process,
but when we are reusing a preallocated child process the RemoteWorkerService
was already initialized and RegisterActor was already called while the
remoteType for the child process was still "prealloc".
This patch fix the failure by deferring initializing RemoteWorkerService in
child processes to when we do receive a non "prealloc" remoteType in
ContentChild::RecvRemoteType.

We want to be able to retroactively tell whether a push was a backstop or not.
This patch stores whether or not a push was a "backstop" directly in the
parameters. The optimization strategy now simply returns 'not
params["backstop"]'.
For simplicity, I'm not counting the 'optimized-backstop' as a backstop. It's
unclear if we'll want to be able to detect these types of the pushes in the
future or not, but we can cross that bridge when we get there.

In the past, the 'backstop' optimization was applied to tasks by default across
all projects, even though it only really made sense on autoland. To choose what
would happen on non-autoland branches, we invented this 'remove_on_projects'
concept.
These days, we only apply the backstop optimization in the first place for
autoland. So 'remove_on_projects' is no longer necessary.

This patch cleans up some of the backstop strategy names. Specifically:
1. Rename 'full-backstop' -> 'backstop'. The old 'backstop' algorithm was
unused anyway, so there is no conflict. It is also just defined directly in
the decorator rather than using 'Alias'.
So now rather than 'full-backstop' and 'optimized-backstop', it's just
'backstop' and 'optimized-backstop'.
2. Remove 'backstop-X-hours-Y-minutes' strategies, and replace them with
the corresponding 'push-interval-X' strategy.
This means we lose the time component in the 'optimized-backstop'. But it isn't
a problem, because we shouldn't be using a time component there at all anyway
(we should just use it with the 'backstop').

NB: This change breaks the IOUtils.read API, requiring that an options
dictionary is passed as the optional second argument, rather than a number
indicating the max bytes to read. This option is not used out of tests however.

This change introduces a `getChildren` method to the IOUtils interface, which
returns an array of absolute paths pointing to the immediate children of a
directory.
This method should provide equivalent (though not the same) functionality to
iterating directory entries using a new `OS.File.DirectoryIterator`.

Despite looking directly at this code while adding the assertion in bug 1660553, I somehow missed that scripted calls were being attached too early. It's not a problem for Ion, because we only inline `FunCall`/`FunApply` if we're calling the jsnative, but it matters for Warp.

The race occurs when the parent changes the owner process for a BC, but the
child does not know about it and proceeds to call SetCurrentInnerWindowId on a
BC it no longer owns. To fix this, in child process, whenever we call
SetCurrentInnerWindowId on a BC, check that the BC is in process and that the
docshell has not been notified about an upcoming process change.
