Previously recommended tab group delete fixes don't work

This is the November 2025 update of this complaint. Pic shows what happens when I control click the tab group I want to delete. (Note the nested folder name. I didn't make that. I tried to call that group "Communities." I guess I got my hand slapped by Safari.) I can't delete that folder/group whatever it is. I can't rename it. I can't delete the Amazon one either to start from scratch. Menu options are greyed out no matter which view I start from.

MacOS 26.0.1; Safari 26.0.1
