Local transitions playing on unmount since 5.38.3 #16826
Description
Describe the bug
When a component has a transition inside an #if block, the out transition will play when the component is unmounted, delaying the component unmount, even if specified as local
From @7nik on bluesky:
"Seems to be caused by github.com/sveltejs/sve... and the fact that the if condition is in fact static."
