If, within a single refresh driver tick, the scroll position is updated by JS
explicitly, and then subsequently also updated by a frame reconstruction, the
scroll origin from the former (nsGkAtoms::other) can get clobbered by the latter
(to nsGkAtoms::restore). The restore scroll origin is "weaker" in that it can
be ignored by the APZ code in some circumstances. This is undesirable because
it means the JS scroll update also gets ignored. This patch ensures that when
setting the scroll origin we don't do this clobbering of stronger origins with
weaker origins.

The spec says that single-line flex containers should stretch their one flex
line to the flex container's cross size, and should ignore 'align-content'.
Initially, the spec defined 'single-line' to include any flex container that
happens to have only 1 line (even if it's got 'flex-wrap:wrap' or
'wrap-reverse'). But later, the term 'single-line' was intentionally redefined
to *only* include flex containers that have 'flex-wrap: nowrap'. So, instead
of checking the line-count, we should instead check 'flex-wrap', when deciding
whether to stretch our one line & ignore 'align-content'.

This patch introduces a new functions named HasEffectiveAnimationOfProperty.
This function checks that a given CSS property is overridden by !important
rules.
On the other hand, now KeyframeEffetReadOnly::HasAnimationOfProperty() does
just check that the effect has a given CSS property. This is used to create
a stacking context because we should create a stacking context for opacity or
transform animations even if the property is overridden by !important rules.

Since we're converting LineReflowStatus to an enum class, the "default:" branch
of LineReflowStatusToString() could be removed as well. In this way, we can add
protection at compile time (warning) instead of runtime (assertion).

This is a pre-patch that uses LineReflowStatusToString() function instead of
LineReflowStatusNames array to support debugging. With this patch, we could
easily regain debugging support from LineReflowStatusToString() while converting
LineReflowStatus to an enum class.

Change the logic that moves the main summary to the front from operating
on generated frames in DetailsFrame::SetInitialChildList() to operating
on frame construction item list in AddFrameConstructionItemsInternal()
so that it will be correct when cooperating with ::first-line.
The root cause of the bug reported is because when specifying
::first-line on details element, the first frame of summary element,
which is generated due to ib-split, will be wrapped in nsFirstLineFrame.
The original code fails to find the summary frame in the wrapper frame
and triggers assertion because of the second ib-split summary frame. To
fix that, we need to descend into the child list of wrapper frames when
checking the main summary.
Add original test case as a crashtest as well as reftests to clearly
reproduce the issue.
Note that in the reftest, the blue color in ::first-line is applied
incorrectly to the second line in the summary due to bug 520605.

KeyframeEffectReadOnly::HasAnimationOfProperty() calls GetAnimationOfProperty()
which checks mWinsInCascade flag and the mWinsInCascade flag is set to true
only if the effect is in-effect.
That means nsLayoutUtils::HasCurrentAnimationOfProperty() actually represents
that a given frame has at least one animation which is current and *in-effect*
(i.e. active).
