The <content> in an XBL document could be injected into documents with
different style backend types. Therefore, we need to set the XBL document's
style backend to the same as the bound document's so that the style
attribute of the content can be processed by the correct backend. <marquee>
elements in xbl-marquee.xml is one such example.

We assume those XBL documents without a bound document use gecko style
backend. Their backend type will be explicitly set when loading in Part 6.

Currently, attribute and child arrays (implemented in dom/base/nsAttrAndChildArray.h) start out empty. When cloning, the array ends up being resized multiple times in order to add the attributes and children that are being cloned from the original node. This would be quicker if the array was initialized to the correct size in the first place so that resizes are not necessary.
However, preallocating space for children is only necessary when performing a deep clone. Therefore, an additional parameter is being added to the Clone, CopyInnerTo, and CloneDocHelper methods to indicate whether preallocation of children should happen. Attributes are copied either way, so that part of the array is preallocated in both cases.

The test doesn't verify that the exceptions are reported to the browser console,
but I manually checked that they are. Adding a test for that part could be
pretty annoying.

It's not only inefficient, but also prone to buggyness. Since styles may not be
up-to-date when it happens.
Post a reconstruct instead, which ensures a style flush happens before running
frame construction.

I noticed that our current behavior in ContentRangeInserted is incorrect. Unlike
ContentInserted (where this code lived originally), ContentRangeInserted takes a
start and end element. I'm not sure if we ever take that path for new content that
needs style, but it seemed sketchy. And generally, it seems nice to just always
style new content the same way (though we still need to style NAC by the subtree
root, since it hasn't been attached to the parent yet).
For situations where there is indeed only one unstyled child, the traversal
overhead should be neglible, since we special-case the single-element in
parallel.rs to avoid calling into rayon.
Being more explicit about what we want here also makes us more robust against
the other handful of callpaths that can take us into
nsCSSFrameConstructor::{ContentRangeInserted,ContentAppended}. Currently we
can call StyleNewSubtree on an already-styled element via RecreateFramesForContent,
which triggers an assertion in the servo traversal.
