When glide.ui.advanced system property is activated, Save button on the incident record will just save form even when assignment group is changed, and not show Assign modal - Known Error

When glide.ui.advanced system property is activated, Save button on the incident record will just save form even when assignment group is changed, and not show Assign modal Description Set "glide.ui.advanced" system property as true, open a work in progress incident, and change the assignment group.

Now when clicking on the "Save" UI action (sys id: 57be45af83bdb11039124a126daad3f6) on the UI16 incident record, it will just save without showing the assign modal.

Clicking on the "Update" action shows the assign modal and updates the record.

Steps to Reproduce

1. Navigate to sys_properties.list and open the 'glide.ui.advanced' system property .service-now.com/sys_properties.do?sys_id=ae706e530a96001a00120cb31709c1d6

2. Set the Value to 'true' and save the record.

3. Navigate to Incidents and open any incident in WIP.

Expected behavior - If assignment group is changed, clicking on Save button should give a assign modal pop up.

Actual behavior - Form is directly getting saved.

Workaround When "glide.ui.advanced" system property is true, open a work in progress incident, and change the assignment group.

When Now Assist for ITSM is installed, and you click on the Save UI action on the incident record, it is expected to just save the form. If you prefer, you can just disable this UI Action and go back to the Now Assist for ITSM default behavior with the other UI Actions available. Click on the "Update" action, and this will show the assign modal and update the record.
