I have the exact problem. Have you found any solution?
Same problem, any solution please ?
What doesn't work ?

I have opened A projet Targets, selected Info.
I could resize the Key column at will. Not the Type nor Value.

Can you describe exactly the problem (SO capture is not very explicit of the problem).
When ⌘ + 2 to view the Source Control panel, branch names can be displayed completely.
It might be caused by the same bug.
