-----------
[LBSE] An SVG transform change leaves ancestor layer repaint rects stale
https://bugs.webkit.org/show_bug.cgi?id=323741
Reviewed by Rob Buis.
An ancestor layer caches repaint rects that are derived from the visual
overflow rect that we invalidate during processing of transform attribute
changes. An assertion is hit because we failed to recompute them:
ASSERTION FAILED: repaintRects() => *repaintRects() ==
renderer().rectsForRepaintingAfterLayout(repaintContainer.get(),
RepaintOutlineBounds::Yes)
Source/WebCore/rendering/RenderLayer.cpp(1333)
Fix that by marking the ancestor layers as needing a position update.
