REGRESSION (301965@main): List items that span multiple lines have incorrect
margins when zoomed in/out
https://bugs.webkit.org/show_bug.cgi?id=309757
rdar://172312498
Reviewed by Alan Baradlay.
Margin values computed in `RenderListMarker::updateInlineMargins` are based on
font metrics which are already zoomed. Since `MarginEdge` stores unzoomed
values, and zoom is applied at resolution time via `resolveZoom`, margins get
zoomed twice.
Fix by dividing out the zoom factor to avoid double-zooming.
