[Bug] Keyboard shortcuts for Diff(-block) navigation only work in 'first' Diff-panel instanced

[goran-w]

When I start SourceGit, in the first Diff panel that I visit the diff(-block)-navigation keys (Ctrl+Alt+Home/Up/Down/End) are working. But if I then visit another Diff panel, these keys are NOT working there. If I go back to the first Diff panel I visited, the keyboard shortcuts are still working there.

Examples (below it is assumed that selected items contain multiple diff-blocks) :

• Session 1:

  • Start SourceGit (in History view), select a Commit in log-graph, switch to Changes (the Diff panel), select a changed item (if needed).
    • (Diff-navigation keys are working here.)
  • Switch to Local Changes view, select a changed item (Staged / Unstaged) to populate the Diff panel.
    • (Diff-navigation keys are NOT working here.)
  • Switch back to History view).
    • (Diff-navigation keys are working here, still.)

• Session 2:

  • (Re-)Start SourceGit, switch to Local Changes view, select a changed item (Staged / Unstaged) to populate the Diff panel.
    • (Diff-navigation keys are working here.)
  • Switch to History view), select a Commit in log-graph, switch to Changes (the Diff panel), select a changed item (if needed).
    • (Diff-navigation keys are NOT working here.)

• Switch back to Local Changes view.

  • (Diff-navigation keys are working here, still.)

As can be seen from these two session-examples, the order in which we visit the Diff panels matter. In the 1st visited panel (during ), the nav-keys work fine, but not so in the 2nd one.
