This is really great! Thank you!

I did some tests and works fine. I have found one edge case,
though. Imagine these tabs, consisting of [hint group name]:

[1 g1 A] [2 g1 B] [3 g1 C] [4 g2 D] [5 g2 E] [6 g2 F]

If we go to tab 2 and unset the group or set a new group (e.g.: "g3"),
the tab will not be moved, which will split the group "g1":

[1 g1 A] [2 g3 B] [3 g1 C] [4 g2 D] [5 g2 E] [6 g2 F]

I suspect that 'tab-bar-move-tab-to-group' fails to find another tab of
the same group to move to a closer position, so it leaves the current
tab where it is, without checking if this creates a misalignment.
