Svelte 5: Component leak, each loop components exist even after the array.length === 0, regression

[98mux]

Describe the bug

Pretty sure this is a regression as it worked before i upgraded from svelte v5 32.

See repl

IMPORTANT NOTE: you need to click the "create particles" button quickly, about 5 times, for the bug to appear

Rewriting {#each particles as { id } (id)}
into {#each particles as { id }}
solves the issue

[Prinzhorn]

Seems to be caused by transition:fade not properly removing all nodes

This seems to be fixed now, not sure which update fixed it
