Weird svg transition behavior

[Thiagolino8]

Describe the bug

When transitioning a svg in a else if block the svg appears complete, appears completely, disappears and only then transitions in
Adding a delay to the transition fixes it

Reproduction

REPL

System Info

Playground running Svelte compiler version 5.28.2

Severity

annoyance

draw seems like the most straightforward behaviour out of all the transition lib utilities, but even here I'm not making much further progress narrowing this down.

I thought explicitly setting the delay property would perhaps mean the delay animation object would be guaranteed to be sent before the real animation object, but I was wrong because I'm not seeing where/how explicitly setting a delay makes a difference to the backend flow (despite the fact setting an explicit delay does get the desired behaviour).

At this point I can only speculate there's something on the WAAPI end that likes getting animation objects with explicit properties, but it's just as likely I'm overlooking some detail on the svelte/transition end.
