After the most recent update to community.openstreetmap.org, a strange bug has surfaced: the scroll position will jump to the bottom of the topic whenever my phone screen turns off!
I have captured a screen recording of this happening in mobile Firefox for Android:
Can you try in safe mode to see if it does the same? And does it repro here on Meta?
Thank you for the prompt, it appears that this is due to the better-osm-org user script!
(Checked on Meta, no repro, disabled extensions and was reminded of the script.)
The developer of better-osm-org is here. The script only runs on the main openstreetmap.org domain, not on community.openstreetmap.org. So make sure you don’t have any additional userscripts installed. And tell which script manager you use: Tampermonkey/ViolentMonkey or something else.
The list of domains on which the script runs is here: https://github.com/deevroman/better-osm-org/blob/593f4e74f416e52cf3c18324c2bf79f15befa5ea/better-osm-org.user.js#L31-L58
