A case to reproduce this issue

See the attached case and screenshot.

This issue could be reproduced on:

* WebKit local build
* Safari on macOS 13.2.1 (and presumably lower)
* Safari Technology Preview up to macOS 13.4.1

Temporarily commenting out `[m_layer setTransform:value]` at `PlatformCALayerCocoa::setTransform(const TransformationMatrix&)` could work-around this issue.

Have you tried this on Safari on macOS 13.4 or higher? It should be fixed at that point.
