Breaking: #78759 - Fluidification of EditFileController¶
See Issue #78759
While moving all HTML from PHP code to an own Fluid template the HTML string given to the hook after compiling the output is different now.
The HTML string given to the hook after compiling the output now contains the closing form tag
All installations that append text to the HTML code in the hook after compiling the output.
The hook code has to be changed to insert additional code before the closing form tag.
