When something stops inhibiting screen blanking, don't directly blank the screen

The scenario: You're watching a movie or a video on eg. YouTube, the video is over and auto play kicks in. Since the last user interaction is longer ago then the configured screen blanking timeout, the screen directly starts to turn off, before the next video can start and I have to log in again. This may be bothering for a lot of people.

The suggestion: Instead of directly turning off the screen, it may be better if you count the stopping of the screen inhibiting as 'user interaction', so that the screen blanking timer starts with the end of the video. The screen would then stay on until, eg. the next video starts.

Is this possible to do?

Best Regards
