Problem regarding the video player playback control shortcut keys

Hi @Coursera team
Thank you for the awesome courses.
I would like to report a problem regarding video player on the Coursera website though. I usually am using the laptop to watch the course, and every now and then I sometimes also look up some stuff from the course on the internet by pausing the video. However, every time I click anywhere else on the screen on the lesson video webpage, for example clicking the full screen button, I can no longer control the playback using the keyboard shortcut keys such as the arrow keys to move forward/backward in the video, or spacebar to play/pause, until I click on the video again. This becomes a bit cumbersome.
It would be great if this could be fixed.
