Small problem with flex-wrap

[Echtzeit]

I've made screenshots to illustrate the issue.

Here you can see five items in one row when flex wrap is disabled.



And in this picture you can see only four items in a row with flex wrap enabled, even though there is enough space for five.

Yes, there were five in a row. After one of the recent updates, I'm assuming the server, it changed. I'm using Edge and the Jellyfin Media Player for at least six months now and in both there were five in a row with this code.
