Clicking on the diff view changed files does not open the expected source file

[Franz-Fischbach]

Clicking on the diff view changed files does not open the expected source file.

Steps to reproduce:

1. Record a diff view with a difference in several files, for this example noir_space_ship has been used.
2. Click on the diff files in the bottom left corner

Expected result:
When clicking on main.nr in the diff files the main.nr editor should open

Actual result:
Either there is no effect, or another file is opened, in this case, shield.nr was opened in the editor.
