Heal edits all gone when switching to another fixing tool before sync

Reproducible at least on all recent Adobe Lightroom Mobile for Android versions.

To reproduce:

1. Make couple of applications of the Heal tool.
2. Approve.
3. Without forcing sync from now on (e.g. by switching to another image), switch to another edit menu (than the Fixing tools).
4. Switch back and pick Remove tool.
5. Change your mind and switch to another edit menu (than the Fixing tools).

Expected result:

Previously made Heal edits stay.

Actual Result:

All (Approved!) Heal tool edits are gone (potentially minutes of lost progress), with no way to recover.
