Amend button does not return the widget to commit state
Created originally on Bitbucket by yruslan (Ruslan Yushchenko)
In 2.11 clicking on Amend button does not return to Commit mode as in 2.10.2 and below, although amendment does happen. Clicking Amend button one more time produces an error message with text "[Code: 1]".
Note. Behavior looks similar as in 2406
