(Firefox :: Tabbed Browser, defect)

Steps to reproduce:

1. Open several tabs and click the List all tabs button. You will see a list of all currently opened tabs, which is expected.

2. Select multiple tabs, right click on them and click Add Tabs to New Group. Name this group Temp. A new tab group Temp will be created.

3. Right click on the Temp tab group and select Save and close group.

4. Click List all tabs. You will see the list of currently opened (not grouped) tabs under the Current window section and previously saved Temp group under the Recent tab groups section.

5. Restore the Temp group.

6. Click List all tabs. Now, under the Current window section all your opened tabs (grouped and not grouped) will be show twice.

7. Repeat steps 3-6. Another duplicated list of open tabs will appear under List all tabs -> Current window.

Actual results:

Every time you save and restore a tab group, you have yet another duplicate of all your currently opened tabs under List all tabs -> Current window. Screenshot is attached.

Expected results:

I am not sure if this is a bug, but if it's not, I just don't get the logic behind this. I expect List all tabs to simply show the list of currently opened tabs without any duplicates.

The Bugbug bot thinks this bug should belong to the 'Firefox::Tabbed Browser' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I managed to reproduce this issue on Ubuntu 22 x64 while using Firefox 138.0.4.

However I didn't manage to reproduce the issue on Nightly 140.0a1 and Firefox 139.0b10.
