Bug description

When i am in a folder with tagged subfolders and scroll (far) down/up some tags "vanish" when i scroll back to them.

Steps to reproduce

1. Open folder with a lot of subfolders
2. Scroll around
3. Tags on folders disappear randomly and reappear randomly - but only if they are out of the users visible window area!

• If every subfolder has a tag, they do not disappear, it only happens if some folders have tags.

Sorry for the late response, 'tis holdiay season...

Console output: https://pastebin.com/s0ardge0 (password is your username)
First i clicked on folders without tags (opening folder details) and scrolled around, then i clicked on one with a tag and scrolled around. I changed visible usernames, links and folder names in the output.

Heres a screenshot, the tag isnt visible after scrolling around

Thank you.
Unfortunately without a screencast it's hard to really grasp what's going on.

When loading, you see the tags normally displayed?
And when you start scrolling they don't reappear? Or they're misplaced ?

Sorry, i misread "screencast" as screenshot, here's a recording.
I marked folder 10, you can see the tag dis- and reappearing.

(I also updated to Nextcloud 30.0.4)
