Slur loses keyboard focus on Shift+Tab in Edit Mode

MuseScore r2725 on Ubuntu 9.10

The present tab order for a slur in Edit Mode is inefficient. Every second Tab or Shift+Tab moves the focus away from the slur either to the main toolbar into the zoom settings dropdown or to the document's tab in the MDI of MuseScore.

STR:

1. Press S to create a slur: the slur is automatically in Edit Mode, the 4th handle has focus;
2. Press Shift+Tab to move focus to the third handle of the slur.

Actual results:
The focus goes to the document's tab. Pressing Tab is necessary to move it back to the slur.

Expected results:
The focus goes to the third handle of the slur in order not to disrupt further editing: I suggest the reversed tab cycle

4th slur handle <=> 3rd slur handle <=> 2nd slur handle <=> 1st slur handle <=> (tab bar) <=> main toolbar

Focusing the tab bar doesn't make much sense and could be dropped IMVHO completely.
