When reviewing a changed template in the diffonly view and typing a reason into the input field, than pressing enter on that input field will submit the form, but gives a Internal error: A parameter is missing or invalid.

The button "Accept revision" has the focus, but it works only, when tabbing on that button or click with the mouse.
