Regression 2.18.00-SNAPSHOT, extra clicks "save & close" when you edit "title" in a document.

1. login to quickstart cms
2. navigate to documents-news-mynews1
3. click on edit and make some changes in "title" field only
4. click on save and close button

expected - document should save and exit from edit mode.
acutal - document does not exit from edit mode.

Note - I you click it for second time, then it exits from edit mode.
