@Kevin Thanks for reaching out. I have performed the quick test and I don't see the same behavior at my end.
- Please verify if there are any extension/add-on on the browser that would be disabling the script causing this behavior. Please disable the extensions/add-on to verify the same
- Please clear your cache and cookies/history of your browser and see if it helps
- Try to repro the issue on different browsers/network and see if you observe the same behavior
If you still observe the issue, please let me know as it would need browser/F12 traces along with portal session ID (ctrl + alt + d) to troubleshoot the issue further.
