Description Richard Robinson 2022-11-11 15:51:35 PST 
When a foreign object is inside an SVG, any click event that occurs on the object has it's `offsetX` and `offsetY` relative to the SVG container rather than the element.

Believed to be a regression from https://bugs.webkit.org/show_bug.cgi?id=234524 , which overrode `offsetFromContainer` in `RenderSVGBlock`, causing the `RenderSVGForeignObject`
to use this override and return an offset of `(0, 0)` instead of its proper offset.
