Can't get ondropped to work

[rosshadden]

I have tried many different times to get :ondropped working to no avail. Just simple things like :ondropped "notify-send foo bar" in an eventbox. I've searched github for path:.yuck ondropped and there are hardly any people using this feature, and most of us that are "using" it just have test notify-sends like me (my dotflies are one of the few results 😅).

Are there any special requirements for this to work that aren't mentioned in the docs, or is it just perhaps broken? dragvalue works great and I use it in a lot of places.
