Browser keeps tabs group even if just one tab is remaining
- /e/ version: 2.4-s official
- Device model(s): OnePlus Nord avicii
## The problem
After closing the next-to-last tab of a tab group the browser keeps the group for the remaining single tab.
Until /e/OS 2.3 the remaining task was shown not as part of the group.
**Steps to reproduce**
1. Open a new tab and navigate to a web page. The Tab is shown as single Tab in the Tabs overview:

2. Tap long on any link and choose "open in new tab in group". Now both tabs are grouped together:


3. Close one of the tabs of the group. The group is remaining:


**What is the expected correct behavior?**
If there is only one tab remaining the group view should dissapear.
