Bug 1650620 [wpt PR 24444] - [FragmentItem] Fix DirtyLinesFromNeedsLayout, a=testonly

Automatic update from web-platform-tests [FragmentItem] Fix DirtyLinesFromNeedsLayout This patch fixes a case where |DirtyLinesFromNeedsLayout| fails to mark items dirty for reusing cached lines. When searching for |LayoutObject| needing layout, checking |NormalChildNeedsLayout| and |PosChildNeedsLayout| were not enough. In some specific cases, only |NeedsSimplifiedNormalFlowLayout| was set for the parent inline box. This patch changes the condition to check descendants to |NeedsLayout|.
