  Drop workaround added in 270248 at main and fix the bug properly
https://bugs.webkit.org/show_bug.cgi?id=264279

Reviewed by Nikolas Zimmermann and Said Abou-Hallawa.

The implementation of `isSVGHiddenContainer()` was incorrect and was returning
false for RenderSVGResourceContainer types, even though RenderSVGResourceContainer
subclasses RenderSVGHiddenContainer.

Fix the isSVGHiddenContainer() implementation and drop the workaround recently
introduced in 270248 at main.
