Spacebar triggers "Next File" in View Mode during video playback, ignoring "No Action" setting

[peterdo]

Effect: Spacebar forces navigation to next file instead of pausing the video.

To reproduce:
1. Go to Tools > Settings > Interface > Keyboard.
2. Set the "Spacebar" dropdown option to "No Action".
3. Open any video file in View Mode / Fullscreen.
4. Press the Spacebar to pause or play the video.

Actual behavior:
XnView immediately jumps to the next file/image in the directory, completely ignoring the "No Action" override. It only works as expected if you manually left-click onto the video playback bar first to force widget focus.

Expected behavior:
The Spacebar should not trigger global "Next File" navigation when it is explicitly set to "No Action" in the settings, allowing embedded media widgets to handle the keypress event correctly.
