We want to avoid to have several cached content processes, one for each
preloaded browser (one per window) and one for the preallocated process.
For that we force the preloaded browser to choose an existing process and
during the first navigation in that tab, that leaves about:newtab, we re-run
the process selecting algorithm
This feature isn't currently used or being planned to be used in the near
future and has some overhead that makes it hard to justify to keep around,
so it's better to remove it and revive it from VCS history if we need it
later.
FrameLayerBuilder requires the the (frame,per-frame-key) for each display item is unique. It only enforces this in certain situations though, so there's cases where we've gotten away without this.
Retained display lists introduces more situations where we rely on this, so I've found a few.
MathML nsDisplayNotation and nsDisplayMathMLBar are the two fixed by this patch.
The original duration I wrote is calculated from the m3u8 file this is too accurate without error tolerant.
The state machine will update playback position periodically(UpdatePlaybackPositionPeriodically)
according to the clockTime or max end time from A/Vsink.
So the duration will be variant that I should consider to set the value to a more relaxed value.

Using namespace id fixes this issue because in Gecko, the pref of MathML
(as well as SVG) works in the way that we choose a different namespace
id (the disabled id) for the elements. Those ids are mapped to the same
namespace atom as normal ids, which means if we use the atom, we would
treat the elements like normal mathml elements.

When removing our Windows message loop pumping code in the content
process, a11y code on the MTA thread must have some way to wake up the
main thread. The main thread could be blocked either on a conditional
variable waiting for a Gecko event, or it could be blocked waiting on
a Windows HANDLE in IPC code (doing a sync message send). In the
former case, we wake it up by posting an event to the main thread. In
the latter case, we continue to use the asynchronous procedure call
mechanism.
