65 Form controls (more precise: UNO Controls) in the drawing layer are ... prone to breakage, since they have some
66 specialities which the drawing layer currently doesn't capture too well. In particular, having a living VCL
67 window as child of the document window, and coupling this Window to a drawing layer object, makes things

71 verify those issues are still fixed. (Whenever you have some additional time, you're encouraged to write
