Debug "out of sync" for web extensions using pwa-extensionhost approach

[alefragnani]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.63.2
• OS Version: macOS Big Sur 11.6.1

Steps to Reproduce:

1. Create a brand new web-extension, using yo code
2. Open in VS Code
3. Add a breakpoint on any line of code
4. Build and Start Debugging (which means the pwa-extensionhost approach)
5. Try to run the Hello World command
6. You will notice the breakpoints are out of sync

I'm trying to update my extensions to be web ready, but even being apparently able to produce the web-ready portion of an extension, the debugging process is not working correctly (and I really like to debug stuff on each scenario).

I tried to skip the debugging process and test the extension using the Sideload approach explained in the documentation, but had no success either, as commented here #138623 (comment). In this case, I'm not sure it is an issue in the tooling or my machine.

Thank you
