Conditional Slot Forwarding is not a thing in Svelte 4
If you ever wanted to forward conditional slots up two component levels, you’re out of luck.
<!-- Grandchild --><slot name="label" /><!-- Child -->{#if $$slots.label} <slot name="label" slot="label" />{/if}Conditional Slot Forwarding is probably never gonna be a thing in Svelte 4.
Tan Li Hau has created a PR to make this possible, but Rich Harris closed the PR, stating that snippets (a Svelte 5 feature that replaces slots) will resolve this use case.
We can only hope that Svelte 5 indeed solves this issue — and that porting over Svelte 4 code will not be too much of a pain!
