Bug description

Nemo fails to change window focus after opening file.
Examples include programs like mpv or mcomix, but not some others like xed, firefox.

Steps to reproduce

0. have mpv installed and some video file somewhere
1. open nemo
2. goto the folder
3. double click the video file to open it
4. press right arrow key (nothing happens)
5. mouse click the window
6. press right arrow key (playback goes forward)

Nemo should autofocus the window on opening, so the user does not have to manually focus.
Opening mpv ("mpv myvideo.mp4") on the terminal does not have this issue.

Expected behavior

0. have mpv installed and some video file somewhere
1. open nemo
2. goto the folder
3. double click the video file to open it
4. press right arrow key (playback goes forward)

Additional information

For whatever reason, this issue does not seem to happen with all programs, just some of them.
My guess is that it's because these programs with issues use some older graphics toolkit or something like that, that causes problems.

Using X11, not wayland

Maybe not a Nemo specific problem. Nautilus and Thunar have the same issue too.
