The UI to Compare of a local version to the remote update set version for conflicts is incorrect. It shows local and remote content flipped after importing an update set as retrieved update sets and while previewing.
Steps to Reproduce
Navigate to System Definitions > Script Includes and open the script include named AbstractAjaxProcessor or go to https://<instance-name>.service-now.com/nav_to.do?uri=/sys_script_include.do%3Fsys_id%3Dd65f78c40a0a0b6900196656f35913d3%26sysparm_view%3D%26sysparm_record_target%3Dsys_script_include%26sysparm_record_row%3D3%26sysparm_record_list%3DORDERBYname%26sysparm_record_rows%3D2598.
Change the file and save.
Navigate to System Update Sets > Retrieved Update Sets and import the attached update set LG Test.xml file.
Open the update set from the retrieved update sets list.
Click the Preview button.
A conflict will be reported.
7. From the conflict list (Update set Preview problems), click the Compare with local link on the conflict entry.
The "Compare two updates" page shows that local and remote update content incorrectly.
Import, preview, and commit the attached update set: "update set workaround for PRB1152886.xml". This file provides a version of the UI page where the PRB has been fixed.
Note – It is extremely important that you delete this UI page after you have upgraded to a version where the PRB is fixed.
