This allows lower precision for DOMMatrix when parsing CSS as the CSS spec does not have number precision requirement.

Reusing sessions doesn't actually save that much time and avoids a lot of

Sometime the geolocation test fails because the position is not retrieved
quickly enough, this is OK as we're just trying to make sure that the

The arguments for the respective container elements apply to their immediate
child items, too: They establish a new formatting context as well and presumably
represent page content that can be considered to be logically separate enough to
warrant individual consideration for font inflation.

Our algorithm for dividing a page up into separate font inflation flow roots
seems mostly based on the idea that a new Block Formatting Context (BFC) should
go hand in hand with a font inflation flow root.
Flex containers so far didn't follow that rule, since they technically create a
new *Flex* Formatting Context (FFC) and possibly also because nobody thought
about font inflation when implementing nsFlexContainerFrame.
This leads to all flex containers being counted against the next higher-level
flow root, meaning that a lot of small flex containers can get inflated if their
sum total of text *collectively* exceeds the font inflation threshold.
This alone is likely undesired most of the time, but is then also aggravated by
the fact that our flexbox behaviour under font inflation is somewhat buggy (bug
1142461).
As apart from the different layout rules inside the container, a FFC behaves
very much like a BFC in that it establishes a new formatting context, flex
containers should therefore correspondingly become font inflation flow roots,
too, and therefore be considered individually for font inflation.
As far as I can tell, with this change we'll also match Blink's behaviour in
that regard.
For completeness's sake, we'll make grid containers follow the same principles,
even though hopefully grids on non mobile-friendly pages should hopefully be
somewhat rarer than flexboxes.

In this case, the desired end state is *no* inflation, so we don't need separate
ref-versions of the test pages - the only difference is in the prefs being used.

There is a natural tendency to add new tests at the bottom of the manifest, so
the comment about the lineThreshold pref wasn't entirely accurate anymore.

We don't need to worry about JSCLASS_PRIVATE_IS_NSISUPPORTS, because the only
work we're really skipping here compared to MaybeWrapObjectValue is the
TryToOuterize call, and that only matters for Window objects, which always have
a DOM class.

TryToOuterize fast-path bails out if a bit-check on the JSClass fails. Trying
to avoid that bit-check by checking for a DOM class, which is also a bit-check
on the JSClass doesn't really make sense.
