Repeat shortcut doesn't work as expected in tablature

Issue type

UI bug

Bug description

In a music staff, when in note input mode, the repeat shortcut (R) immediately repeats the last added chord. However, in tablature, the first repeat command advances the cursor but does not enter anything. You have to press repeat (R) again in order to enter the last chord: subsequently the repeat command acts as expected.

IMV, the repeat command should act the same way in tablature that it does in the music staff. That is, the first repeat command (R) should both advance the cursor and enter the last added chord.

Steps to reproduce

1. Create a linked staff/tab score.
2. In the music staff enter note input mode
3. Press 5 (say) to enter a 5 fretmark on the 1st string.
4. Press repeat
5. Now repeat these actions in the tablature staff.

Actual result: In step 5, the first repeat command advances the cursor only.
Expected result: In step 5, the first repeat command should advance the cursor and add the last chord.
