Initial Focus in Diff-Editor is sub-optimal

• Choose Tools -> Git -> Current Project -> Log
• Click on a commit
• Diff Editor opens with Side-by-Side-Diff and the Commit message on top
• Try PageUp/PageDn/CursorUp/CursorDown keys: nothing happens
• Press Tab one time: cursor goes to the commit message
• Press Tab another time: cursor goes to the diff window

Expected:

• cursor should be either in the commit message or the diff window instantly
