[MultiColumn] Ignore spanner boxes inside <legend> https://bugs.webkit.org/show_bug.cgi?id=209248 <rdar://problem/51857865> Reviewed by Simon Fraser. Source/WebCore: <legend> boxes don't participate in the multicolumn flow, they are simply ignored. This patch ensures that we don't include their descendants in the spanner construction. <column>some<legend><div spanner></div></legend>content</column> <- the "spanner" div won't span the column content. Test: fast/multicol/spanner-inside-legend-crash.html * rendering/updating/RenderTreeBuilderMultiColumn.cpp: (WebCore::isValidColumnSpanner): LayoutTests: * fast/multicol/spanner-inside-legend-crash-expected.txt: Added. * fast/multicol/spanner-inside-legend-crash.html: Added.
