This PR fixes #131407
When a service worker is started, the creator sends a message to verify its version. Sometimes this message was being sent to an older, already existing service worker. As a result, the
workerReadypromise would never resolve and the webview would stay in a loading state.The best way I found to test this was to load a jupyter notebook ("Jupyter: Create New Blank Notebook) in a browser environment (I used https://github.com/cdr/code-server for that) in Firefox. It happens in Chrome too (~10% of the time), but it's more common in Firefox (~50% of the time).
