Title action should let the cursor on the same line

When I click on the title action, the cursor move on the next line. When I click again the markup symbol = is appended again and the cursor move to the next line. This give the impression that the action is removing lines because the editor scroll down and the title disappear.

The behavior is also not consistent with other actions, first click add the markup symbol, second click remove the markup symbol.
