Deleting a tab group also deletes the exported bookmarks

[limedaniel]

If you export a tab group to a set of bookmarks then delete that tab group, the bookmarks are also deleted.

To Reproduce

1. Create a new tab group
2. Add some pages to it
3. Open the menu and right-click on the group
4. Select Export group to bookmarks
5. Note that a new folder is created in your bookmarks under the name of your group.
6. Open the menu again and right-click on the same group
7. Select Delete group
8. Note that the group is gone, and so are the bookmarks you just exported

Expected behavior

I'd expect the group to be deleted but the bookmarks to remain

Desktop (please complete the following information):

• OS and version: Ubuntu 20.04.2 LTS, GNOME 3.36.8
• Firefox version: 86.0
• Simple Tab Groups version: 4.7

I'm frustrated by this too. I want to retire some groups but still want their contents hanging around as bookmarks so I exported them first. ...and then I had to restore them from backup because it deleted my exports when I deleted the groups.

So then I tried again by renaming the exported folders and moving them somewhere else than the default STG export folder. They still were deleted even though they have a different name and were in a different folder.

This is v4.7.2.1 running on FF 96 under Kubuntu 21.10 and I've even tried with the "Leave bookmarks of closed tabs" box checked.

Hm. I also use the "Export tabs to 'STG Bookmarks' folder" option. One solution could be, if that checkbox is selected, to have STG only delete bookmarks if they're in that folder?

I gotta say this is a surprising behavior as well. An option to "not delete bookmarks when closing group" would meet the need.
