[IFC][Partial layout]
InlineItemsBuilder::m_isNonBidiTextAndForcedLineBreakOnlyContent may get stale
with partial content
https://bugs.webkit.org/show_bug.cgi?id=261373
Reviewed by Antti Koivisto.
m_isNonBidiTextAndForcedLineBreakOnlyContent tells whether the _entire_ IFC
content is text and/or forced line break only.
This patch fixes the case where the partial content is indeed text and/or
forced line break, but the non-mutated part of the content has other type of
boxes.
As the first step of inline item collection on partial content, we traverse the
inline tree starting from the root
all the way to the damaged box while pushing/poping subtree roots. It ensures
that we can continue collecting mutated content
even when it is nested inside inline boxes
e.g.
This is old <span>content but here <span>we've got some newly appended and
nested content</span><span>
During this initialization we can also check for
m_isNonBidiTextAndForcedLineBreakOnlyContent.
