Steps to reproduce
Create a composable that have onScopeDispose
Execute in SSR
What is expected?
onScopeDispose isnt triggered, that normal because there is no reactivity in SSR, so no need to trigger cleanup hook.
onScopeDispose never trigger.
What is actually happening?
onScopeDispose is triggered in 3.5.31
the behaviour changes since this version, it's a breaking change.
