hello, +1 for this feature

build should not be broken if we use svelte:element (error Valid <svelte:...> tag names are svelte:head, svelte:options, svelte:window, svelte:body, svelte:self, svelte:component or svelte:fragment)

thx

Migrating GH issues to YouTrack. I've created a new issue: WEB-62309 Svelte: add completion of svelte:element

the rest should be supported already via WEB-58397 use the svelte language server.
