Console stops inserting line-breaks under specific conditions

Basically an extension of MCL-7216 . When that bug happens this does as well.

Steps to reproduce (as copied from there):

1. In the settings, tick the "Keep the launcher open while the game is running"
   and "Open output log when the game starts" settings.
2. Start the game.
3. Quit out of the game, [might be necessary to get a crash].
4. Click the dock icon a couple of times.
5. New windows should open, one per click.
6. Try to resize, focus, or by any other way interact with the console.
7. Automatic line-breaks are not inserted after the window ends - text continues as if it is unlimited.
8. Also scrolling sideways (using magic mouse, or trackpad) is not possible - but that may be just because it's not needed during normal operation.
