    Disable DropTarget interface temporarily
    
    Drag and drop handling is one of the areas that saw major changes
    in GTK4. Those changes are very very welcome, but too major for
    a polyfill, and too significant to hide adapting to them in a
    general "port to GTK4" commit.
    
    So to allow for a separate port, just stop calling the code for now.
