Additional context

I could fix this by using onerror="" instead of svelte’s on:error={}.

I could fix this by using onerror=“” instead of svelte’s on:error={}.

@Rich-Harris This works. I suppose that event listeners that originate directly from HTML elements can be attached at the right moment?

The language server seems to complain about that. Should I open a new ticket somewhere?
