- Files that used StaticPrefs::layout_XYZ() API or gfxVars::XYZ that needed an
include. (Addressed by adding the missing include.)
- Files that use mozilla::dom::XYZ or mozilla::gfx::XYZ without qualifying the

nsFloatManager can be triggered with
wm-propagation-body-dynamic-change-002.html added in Part 3.
Add the test as a crashtest because web-platform reftest doesn't seem to

Add reftests to verify that BFC bits are added to the child block if the
parent and child has the same block-direction, but different sideways

Frames split by column-span are linked together by non-fluid
continuations. We want GetLogicalSkipSides() to recognize that. The
documentation in nsIFrame::GetLogicalSkipSides() already
uses *continuation* rather than *in-flow*, so no need to adjust the
wording.
However, after patching GetLogicalSkipSides(), the first column-content
after a column-span split starts to skip the block-start side because it
has a previous continuation. We want the content in the first column to
consider applying its block-start margin. Hence the modification in
BlockReflowInput's constructor. (Note that the first column-content is
always a block-start margin-root, which is fixed in the previous part.)
This is necessary to avoid breaking
testing/web-platform/tests/css/css-multicol/multicol-span-all-margin-bottom-001.xht
In multicol-span-all-children-height-006.html, add "margin-top: 1em;" to
the container to expose the bug if we still check GetPrevInFlow() rather
than GetPrevContinuation() when computing applyBStartMargin in
nsBlockFrame::ReflowBlockFrame().

This patch changes behavior only if column-span is enabled. It fixes a
lot of fuzzing test cases which will be added in the next part.
It changes the column balancing behavior in the following ways.
1) By using unconstrained block-size to measure the last column in the
first balancing iteration, we can guarantee that mKnownFeasibleBSize
has the correct feasible block-size.
2) Always reflow one more time if the content cannot fit in the
available content block-size. Due to 1), the content (last column)
always returns fully complete in the first balancing iteration even if
it's in an inner column with a constrained available block-size. We need
to reflow again to get the correct *incomplete* reflow status so that
the outer column can create next-in-flows for the inner column.
3) ColumnSet gives up balancing only when ColumnSetWrapper is running
out of block-size. When a ColumnSetWrapper has constrained block-size,
i.e. it's in a fragmentation context like pages or nested columns, we
prioritize fragmenting ColumnSetWrapper over creating overflow columns
within the nsColumnSet.

Before bug 1411422, a ::-moz-column-content has height:100%, so it could
go into this path if ColumnSet's available block-size is unconstrained.
However, after bug 1411422, height:100% was removed for
::-moz-column-content. That is, its computed block-size is
unconstrained, so it can't go into this path. This applies regardless of
whether column-span is enabled or not.

After enabling column-span, ColumnSet becomes an anonymous child under
ColumnSetWrapperFrame. It doesn't need to handle border and padding,
containment, and non-auto block-size. ColumnSet's final block-size is
simply the union of ::-moz-column-content frames' rects.
However, we should extend ColumnSet's block-size to consume the
available block-size if the ColumnSetWrapper's block-size is constrained
so that the column rules are drawn to the block-end edge of the multicol
container.

In frame construction, a block can be split by column-spans into several
fragments and each of the fragments is chained together by non-fluid
continuations. Later in reflow, each fragment can create its own fluid
continuations due to reasons such as the constraint of its available
block-size.
The main idea of this patch is that we calculate the block's final
block-size by shrinkwrapping the children for every fragment except for
those fluid continuations after the final column-span. To do that, we
need to correctly tag each non-column-span-wrappers
nsIFrame::HasColumnSpanSiblings() except the last one.
We also need to modify nsSplittableFrame::ConsumedBSize() so that it
includes the block-size for both fluid and non-fluid continuations.

As described in https://bugzilla.mozilla.org/show_bug.cgi?id=1562122#c5,
this precomputed argument is not our children's block-size, but is the
block-end edge of children because aState.mBCoord is initialized as our
border-padding block-start in BlockReflowInput's constructor.
I also delete the sentence "The final block-size that is used in
aMetrics will be set ..." because this is the implementation details of
this function, and is likely to become inaccurate after considering the
block split by column-span.
