Hello,

I'm encountering an issue in Webkit / Safari with a ResizeObserver not firing if the observed element is an SVG element.
The tested browser is Safari desktop 16.3.

The same code was working fine on Chrome and Firefox.

Thanks for reporting this bug. Can you please attach a reduced test case which does not work as expected in WebKit?
