-----------
[LBSE] A scrollable outermost <svg> never computes its scroll dimensions
https://bugs.webkit.org/show_bug.cgi?id=324037
Reviewed by Anne van Kesteren.
ASSERTION FAILED: !m_scrollDimensionsDirty
Source/WebCore/rendering/RenderLayerScrollableArea.cpp(1216)
An outermost <svg> with a non-visible overflow gets a scrollable area, but
RenderSVGRoot::layout() never refreshes the scroll dimensions like RenderBlock
does.
Refresh them at the end of layout, after overvloew has been computed. The actual
scrolling logic needs to be revisited - it is neither spec compliant nor works
as intended. However, this is a first stab at fixing it properly in LBSE.
