[RenderTreeBuilder] Reset the "children inline" state when merging anonymous table boxes
https://bugs.webkit.org/show_bug.cgi?id=225266
<rdar://77327951>
Reviewed by Simon Fraser.
Source/WebCore:
This patch fixes the case when we end up moving block level boxes to an anonymous table box (cell, row) which previously
had inline level boxes only (it happens when the destination ("to") table box has no in-flow children).
Test: fast/table/merge-anonymous-table-cells-with-block-children.html
* rendering/updating/RenderTreeBuilderTable.cpp:
(WebCore::RenderTreeBuilder::Table::collapseAndDetachAnonymousNextSibling):
LayoutTests:
* fast/table/merge-anonymous-table-cells-with-block-children-expected.txt: Added.
* fast/table/merge-anonymous-table-cells-with-block-children.html: Added.
