Filings UI: The "Unsaved Changes" pop-up appears even when the user resets the filing to its original state.

**Describe the bug in the current situation**

When a user makes changes to filings, such as COD/COA, and then reverts those changes, leaving the filing in its original state, clicking "Cancel" still triggers a pop-up warning that unsaved changes will be lost. This behavior is unexpected since the filing has been restored to its original state.

Steps to reproduce the behavior:
1. Go to 'https://test.business.bcregistry.gov.bc.ca/BC1156192/'
2. Start a COA/COD filing.
3. Make some changes and revert those.
4. Now click on Cancel.
5. Observe that the Unsaved Changes Pop-Up shows up.
