Microsoft Edge reinstalls extensions after using web-ext

[Juraj-Masiar]

Is this a feature request or a bug?

BUG - but likely in Edge, although may be fixable here.

What is the current behavior?

STR:

1. Have a Edge browser with some extensions installed. You may also need to be logged in your Edge account.
2. make sure it's fully closed, for example by running:

taskkill /IM msedge.exe /F

3. in your extension folder execute web-ext with msedge.exe path:

web-ext run -t chromium --chromium-binary "C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe"

4. wait a few seconds and close the browser, just in case, use taskkill again:

taskkill /IM msedge.exe /F

5. open your normal Edge and observe how it's missing all extensions and how they are being installed one by one.
   The storage seems to be not cleared but the post-install pages are opened for each extension.

What is the expected or desired behavior?

The normal Edge should not be affected by "web-ext run".

Do you have access to a non-Windows machine or VM? If yes, can you try to see whether you can reproduce this issue on non-Windows (e.g. Linux or macOS)?

Can you also reproduce without web-ext at all? For example:

"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --user-data-dir=%TMP%\profdir --load-extension=absolute\path\to\your\ext
