Advanced fraud protection erroneously suggests changes may not be saved

[csmcneill]

Describe the bug

When editing the advanced fraud protection settings, there is a warning modal that appears when navigating away from the page:

[siteurl] says

There are unsaved changes on this page. Are you sure you want to leave and discard the unsaved changes?

And selecting the Back to Payments Settings button produces a similar modal with different copy:

Leave site?

Changes you made may not be saved.

This modal appears even if no changes were made or the changes were saved. In my limited testing, I couldn't get this message to not appear.

To Reproduce

1. Enable advanced fraud protection.
2. Edit the advanced settings.
3. Make no changes.
4. Attempt to navigate to another page.
5. Note that you receive the warning modal.

Also:

1. Enable advanced fraud protection.
2. Edit the advanced settings.
3. Adjust one of the settings.
4. Select Save Changes.
5. Select Back to Payments Settings.
6. Note that you receive the warning modal.

Actual behavior

There is a warning that changes may not be saved even if no changes were made or changes have been saved. This is unnecessary and adds confusion.

Screenshots

Expected behavior

If there are no pending changes, this warning should not be present.

Additional context

Tested in versions 7.5.3 and 7.6.0-test-2.
