• [ ] I did use the incredible bugreport to markdown converter to paste bug reports.

  Context

• Device: Nexus 5X

• OS version: Android 8.0.0
• App version: newest dev branch (13/12/2018)

Describe the bug

If the video is playing in full- screen mode, when I lock the phone (shut up the display), the video will be paused. But if the video is playing in pop-up mode, lock the phone won't pause the video.

How to reproduce

Play a video in pop-up mode and lock the screen.

Expected behavior

The video should be paused, like full-screen mode.

Can confirm, having the same problem on an LG VS988 on 8.0.0 with the latest NewPipe version.

I believe this is intended behavior. There might be the need for a setting to be made to make this optional though.

Does Settings -> Video & audio -> Minimize on app switch suit your needs?
