• I have read the contribution guidelines given at https://github.com/TeamNewPipe/NewPipe/blob/HEAD/.github/CONTRIBUTING.md.
• This issue contains only one bug. I will open one issue for every bug report I want to file.

Steps to reproduce the bug

1. Enable the option "Ask for confirmation before clearing a queue".
2. Add a single track to the background queue (either playing or paused).
3. Play another video in NewPipe normally.

Actual behaviour

The video starts playing, and background queue is deleted.

Expected behavior

A warning "The active player queue will be replaced" should appear. Just because I have only one track in the queue, doesn't mean that I want NewPipe to remove it without warnings.

Device info

• Android version/Custom ROM version: Android 11
• Device model: Pixel 3a

@nbmrjuhneibkr you or anyone else can remove this line:
https://github.com/TeamNewPipe/NewPipe/blob/dev/app/src/main/java/org/schabi/newpipe/fragments/detail/VideoDetailFragment.java#L2078

And get the behavior you want. I didn't think that one stream is important and shouldn't be replaced.

Is "just edit the code and build the app yourself from now on" going to be the official fix for this?

Instead of being limited to yes or no, "Ask for confirmation before clearing a queue" could have 3 options: always, never and "when the queue contains multiple tracks".

@nbmrjuhneibkr nope, I just showed the place that fixes the problem. Anyone that can make a PR can made a fix based on info I provided. It may be even you. Or @opusforlife2 if he wants.

@opusforlife2, yeah, I think so.
