deno lsp: WebWorker will not be treated as Module

[starkpsmichael]

Thought this was already fixed in #8914?

Using latest deno canary and actual vscode-deno.

Adding a export {} to the file helps.

Actual Result

Expected Result

File will be formatted.

#8914 doesn't really have anything to do with this.

Can you provide a more complete reproduction, specifically the code snippet where you were importing the file where you added export {} to it?

@kitsonk
worker.ts: keep empty
main.ts:

const worker = new Worker(new URL("worker.ts", import.meta.url).href, {
  type: "module",
});
worker.postMessage("");
// and then type anything will trigger this failure
