Svelte 5: nested transition is buggy

[dm-de]

Describe the bug

One transition inside other transition do not work correct - when {if} block is used. Similar code work with Svelte 4.

Reproduction

What should happen, if you click button:

1. a overlay should fade smoothly
2. a panel should fly smoothly

But only fade works. Panel do not fly.

Open Overlay.svelte and remove {#if} block - but do not remove {@render} Now, this happens: -fade do not animate smoothly -but panel fly as expected
