System Configuration: saving a setting as a favorite doesn't work

[StefanAbel-OTOBO]

When you tray to save any setting (I tested it with CustomerColorDefinitions) as a favorite, it jumps a bit upwards and doesn't save it.

1. Go to Admin > System Configuration
2. chose any setting of your liking
3. click the setting name for the "dropdown" to appear
4. click "Add as favorite" and see that it jumps up, and doesn't actually save it as a favorite.

So I cannot actually save the setting as a favorite at all.

Tested on Demo system with OTOBO 11.0.6 and on customer's system 11.0.7 with macOS Safari and Windows Microft Edge, also after Maint::Cache::Delete and Maint::Loader::CacheCleanup.

Further information: I was not able to reproduce this on code state 397fc6b and Firefox.

From a quick chat with @StefanAbel-OTOBO: The bug did not show up when trying it with the Namespace setting.

After reviewing the issue, it was reproducible. The behavior occurs if more than one sysconfig setting is displayed on the screen. In the browser console I noticed that no request is sent to the backend in this case, this would point to a JavaScript bug.
