Svelte 5: Values within a function inside a $effect don't trigger an effect re-run

[Xeronic]

Describe the bug

When using a setTimeout with a function containing a signal inside an effect to create a debounce effect, the timeout is not re-run when the signal is updated. Not sure if this is a bug or feature since the signal is within a function and not directly under the effects scope.

Probably a duplicate of:

• Runes: Dependencies not fully tracked in async functions #9309

If you have dependencies in an asynchronously executed bit of code, evaluate them at the start of the effect.

In case this is not part of some checklist yet: The final docs should visibly note this limitation.
