Relative-sized SVG resources are not invalidated on viewport size change

Without digging into it, I'm guessing we don't register hidden resources for relative length invalidation (as we do with regular elements).

At a quick glance, we don't seem to fire InvalidateSVGRootsWithRelativeLengthDescendents for div size changes.

Not sure how this works for e.g. GeometryElements at all...

Ugh, resource containers get special treatment during layout - this I believe is the root cause (ignoring force_child_layout at this level): https://cs.chromium.org/chromium/src/third_party/blink/renderer/core/layout/svg/svg_layout_support.cc?rcl=94a729903406cc33d7b18c6be41d36362465e132&l=349

Unfortunately, it's intentional...
