(Firefox :: Session Restore, defect, P2)

Description

[Jeremy Swinarton]

Steps to reproduce:

1. Open some "worth-saving" tabs. Put some of them in a tab group.
2. Right click the tab group label and select "Delete group".
3. Close the rest of the ungrouped tabs.
4. From the top menu, go to "History > Recently Closed Tabs > Reopen All Tabs".

Expected result:
All tabs are reopened, and the tabs that were closed through deleting the tab group are reopened as part of a group.

Actual result:
All tabs are reopened ungrouped.

I was able to reproduce the issue on an affected Firefox Nightly 136.0a1 build from 2025-01-15, using Windows 11.
Verified as fixed on Firefox 136.0b3 using Windows 11, macOS 14.7 and Ubuntu 22.04. Closed tabs deleted as a group are reopened as part of a group.
