Catalog task (sc_task): Form goes partially unresponsive after previewing a Reference field. It happens only few catalog tasks form.
Cause
The reference field's table:Requested item, is configured with Variable editor on its sys_popup view.
If there are any client scripts/ui policies configured on the variables (Requested Items), they will try to execute even when loading the variable editor on sys_popup view and won't get executed, this will cause for the issue
If there is no sys_popup view exists for the table: sc_req_item, it will load the Default form view of sc_req_item. It is always recommended to create a sys_popup view without a variable editor.

Sometimes, the issue might occur due to the custom ui macro (formatter) or script include assigned with the Reference field's dictionary or on the form layout.
