Empty space reserved for dock sometimes remains when scrolling downwards through the feed

[ClockGen]

I can't determine the exact reproduction steps, but when option "show behind dock" is disabled, sometimes dock retracts but the free space behind it remains and the feed doesn't expand to full screen.
I'll try to update this issue with more info on under which conditions it happens.

UPD: the bug seems to happen under these conditions:

• "Don't show until user scrolls" is enabled in feed settings
• "Collapse notifications" is disabled in notification settings
• A notification is added or removed when user is scrolling feed (not sure about this one)

does it happen on 1.14?
