Pop-up message "Changes you made may not be saved" appears when moving away from RITM without making any changes if List collector variable is present in the form

A popup message stating changes you made may not have been saved appears from browser while moving away from RITM page although no changes have been made to the page.

After investigating on a number of test scenarios, the issue was found being caused by the List Collector variable. If the selection from the list collector on the Catalog item is not in the same order of the entries on the referenced table it will populate a save message when navigating away from the RITM record even though no changes have been made.

The issue is reproducible when we select the List collector values from bottom to top.

1. Configure an Item which as a list collector with User table mapped as reference.Example here is Apple iPad3 item.
2. Open Service Portal.
3. Search for Apple iPad3 Service Catalog.
4. Select the values in Select User list Collector variable. Please select the value from bottom to top. Example: In the list collector Alejandra Prenatt comes later to Aileen Mottern. So first select Alejandra Prenatt and then Aileen Mottern.
5. Submit the record.
6. Open the RITM from the platform by going to sc_req_item table.
7. Open the RITM record and let the page load completely.
8. Close the RITM tab or refresh the page without making any changes. Notice that the pop-up message showing: Do you want to reload this site?

This problem has been fixed. If you are able to upgrade, review the Fixed In section to determine the latest version with a permanent fix your instance can be upgraded to.

The workaround is to add the glide_list attribute to the List Collector Variable which is causing the issue.

Alternatively you can set the glide.ui.dirty_form_support property to false, but this is system wide and would not be recommended for the effects it would have on all the instance forms.
