Edit again will see unsaved value from previous cancelled edit

* What happens
If you edit some row, then cancel it, then edit again, you will see previous unsaved values in the field.

* What's expected
Literally, a "Cancel" button should mean to discard the changes. However, the changes are saved internally. It might make sense only if there is an additional "Reset" button, which is missing from the current design. Consequently, I believe the current behavior is wrong.
