Clickable things in output area don't accept enter presses

[Akuli]

Steps to reproduce:

• Create Python file that contain syntax error. (or any other error).
• Run it in Porcupine, with output not going to external terminal. (Press Shift+F5 and select "Display the output inside the Porcupine window".)
• Press Alt+Shift+C to focus the output area. (or just click output area)
• Use arrow keys to navigate on top of File "...", line 1.
• Press enter key.

Expected result: The line in question is highlighted in editor (just like it is if clicked instead of enter key)

Actual result: nothing happens
