Svelte 5 (alpha 90): broken svelte transitions with `{@render children()}`. Issue starts from alpha 82.

[svelte-kit-so-good]

Describe the bug

I'm noticing svelte transitions are broken for a Modal component I have ... but only starting in alpha 82 and if I use {@render children()}.

• if you replace in:scale with in:scale|global everything works
• if I use <slot/> instead, it works again

Reproduction

• original REPL with tailwind
• simplified REPL with vanilla
• stackblitz showing alpha 81 works (update alpha to > 81 to see bug)

Logs

No response

System Info

Svelte v5.0.0-next.90 (broken since alpha 82)

Severity

annoyance

[socketopp]

Dynamically expanding does not work due to transition:slide={{ duration: 250, easing: cubicInOut, axis: 'y' }}
