Virtualmin odd display behaviour

SYSTEM INFORMATION
OS type and version EL9 and 10
Webmin version 2.621
Virtualmin version 8
Webserver version apache

Check this out, follow the sequence exactly, it happens on 3 servers that I have tested.

Virtualmin, select a domain that has it’s website on your VMin server.
Web Configuration → Preview Website - it opens in another tab
List Virtual Servers - The Users column now shows user count as eg 10 (List..) instead of the normal number only with mouseover showing List.
Click on the (List..) - weird things happen. Maybe a 404 Not Found, Maybe a messup of bits of the previous website.

Just click Dashboard to return to Webmin display, then you can click List Domains and it’s all back to normal.

On my old VMin server that I am replacing it has caused php 7.4 to stop, restarting php fixed that.
