Impossible to pass key blocks through slots

[alextana]

Describe the bug

I'm trying to use a key block to rerender a component based on a condition, but I noticed that if a component is nested it looks like it doesn't actually get re-rendered

Reproduction

https://svelte.dev/repl/990bc381eae748a2822c3d07304d14c2?version=3.46.5

the behaviour I'm expecting is to get Component3 to log 'mount' when reset changes

@alextana Interestingly, if you pass the key into the nested component as a prop, it works as you expect it to: https://svelte.dev/repl/28bfa9addc014a8586ea88a03ed1e80e?version=3.46.5

Yeah, that's interesting and it works well enough for me to close this, thanks a lot @kindoflew :)

even if it's possible when it's passed as prop, can we let this open, so we can fix original issue in compiler?
