bug: slot property seems undefined when referred in select elements scope

[CatchABus]

Describe the bug

If I refer to a parent's slot property inside a select element with a binding value, an undefined error for slot property will be thrown if selected option is changed by user.
This doesn't have any effects on functionality but it still throws an error that fills console on every selection change.

Reproduction

https://svelte.dev/repl/fe9ca7db7ce140d3ade4a3e7b53d7b94?version=3.42.4
Select a new option and check console output.
