Nested menu not working since Svelte 5.33.5 on Firefox

[rChaoz]

🐛 Bug report

The menu works correctly with Svelte 5.33.4, and is broken in 5.33.5, on the latest version of Firefox apparently. After some debugging, it seems like the parent ref remains null, even though it is set. This affects multiple things, but, for example, the pointerleave event no longer hides the nested menu, causing it to remain visible forever, this is shown in the reproduction below.

Note that this seems to be a state issue and likely affects more components, not just the menu.

It appears to be already fixed in the latest Svelte (5.33.15). I've bumped the version, and it works correctly.

Please bump the version and try again.

Side note: Svelte releases have been quite volatile lately. We'll keep an eye on the updates

Hi thanks for the response! However the issue is not fixed, maybe you tried in Chrome/Chromium? The issue is Firefox-only.

@segunadebayo could you maybe please try reproducing using FF on latest Svelte version and re-open this, thanks! If you can't reproduce it let me know so I'll take a better look
