The card completion mark is reset if changes were made to the completed card

[Nastia1995]

1. A user creates a card and assigns someone responsible for its completion.
2. Another user sets a "completion date," and the card is saved.
3. Then, they open the card and change the description (for example, by selecting "Callout" in the action palette, then "Done"). They enter any text.
4. Close the card; changes are saved.
5. After some time, the completion date is reset, and the "Mark Completed" button becomes available.
6. Information about the card's completion appears in the activity history.

I request a correction. It is expected that after changing the description of a completed card, its completion will not be reset.

This is reproducible.
