Bugfix
Detail
#24551
GUI Inspector dialog no longer opens for buttons
In ImageButtonRenderer, the control CSS classes are written twice. This leads to the fact that the GUI inspector cannot examine any more buttons, since this determines the ID of the control by a CSS class. The Control CSS classes should only be written at the top element of the button.
Test
Examine a button with the GUI Inspector in demo. Expectation: A GUI Inspector dialog opens.
