Severity: 4-Minor


1. Create fps profile with a "Additional function to be run before JavaScript load" (BLFN) configured. 2. Clone this profile. 3. In the cloned profile choose another profile to defaults from (where there is no BLFN). 4. Save configuration.


The original BLFN is still configured on the profile (should have inherited the empty BLFN from parent profile).


- Current profile has a BLFN configured. - New parent profile has no BLFN.


1. Use tmsh. 2. Refresh before save.
