5. Swipe down to go to mini-player
6. The first swipe down gesture moved the feed position upwards

The position should be unchanged

The position is changed as if the swipe down was used in the feed not the fullscreen player

It turns out that it's not the gesture itself to blame. I used the fullscreen button and it still happens. It moves the feed to the top (latest video). It seems to be intermittent too.

This bug is only expressed when going into landscape mode. When setting the fullscreen mode to portrait, the bug does not occur.

A little more testing shows that any screen rotation transition resets the scroll position in all video feeds. You can replicate this by setting General > Screen Orientation to "Auto-rotation".

I also noticed that not all scrollable lists were affected, such as subscriptions and settings. I could only get it to occur on the video feed lists.

I've tracked it down to be this issue: material-components/material-components-android#3473. Not sure if there's any workaround for this 🤷

The issue applies for the subscriptions, watch history and the views for looking at a channel or a playlist. (SubscriptionsFragment, WatchHistoryFragment, ChannelFragment, PlaylistFragment)

Correction: by "subscriptions", I meant the view that enumerates your channel subscriptions. The subscriptions video feed is indeed affected.
