Make tab groups collide at single-click like every other button

[phonics8226]

Buttons are universally activated with a single click; what is the reason for toggling tab groups with a double-click? It also doesn't have a pointer cursor, which is another standard visual cue for buttons.

Agree fully, one click to open and close a tap group; now it is double-click

I have another problem. if I open a new website in the last one of one tab group, the new tab is not opened in the same tab group (as expected) BUT it opens the next tap group and put the new tap in the next tab group. This must be a bug as it is very much un-acceptable.
