Enabling this extension, under certain configurations, makes external applications (like firefox example.com from the commandline, or opening bookmarks) open links in two duplicate tabs instead of one.

To Reproduce
Steps to reproduce the behavior:

1. Enable the extension
2. set the When an external application opens a tab setting to Open in last active container
3. open a tab in a specific container (not the default one)
4. open a bookmark in a new tab
5. See two tabs opened instead of one

Expected behavior

Only a single tab should be open.

If you cannot find any errors there, try opening the browser console (hamburger menu > more tools > browser console).

**Additional context**

I have many other extensions but managed to bisect the problem to this specific extension.. but it's possible it manifests itself only in combination with others.

not reproduced on my mac... if this kind of thing changes depending on platform it is very weird 😭 ...
