Save the Issue summary on tab as well as enter (BB-1398)

Issue #2574 invalid

When editing the title of an already existing issue, pressing tab changes the field focus but does not save any changes made.

To actually change the title, enter/return must be pressed after making the changes. There is no graphical indication that this is what must be done.

I'm suggesting that pressing tab saves changes in addition to the return/enter keys.
