Dropcursor won't remove the cursor if default drop event is prevented from custom handler

[eric-burel]

Hi,

I couldn't build a repro because the Glitch doesn't allow to require prosemirror-dropcursor, but the bug is simple:

1. Install dropcursor
2. Write a custom drop handler that calls event.preventDefault(). I do not return anything from this handler.
3. Drop something: the cursor stays up for 5 secondes instead of 20ms because "dropcursor" never catches the drop event

It seems to me that dropcursor should have a kind of "priority" over the default drop handlers. Removing preventDefault() from my custom handler is possible but perhaps not recommended are you are supposed to call it in drop event handlers when you accept the drop, unless I misunderstand something specific to prosemirror.

Returning "true" at the end seems to have no effect.

Does putting your custom plugin after the dropcursor plugin in the extension array help?

[eric-burel]

It's a custom event handler, defined using  handleDOMEvents, so not a plugin I would have tried that otherwise.

Edit: perhaps there is a way to have a plugin to add events to "handleDOMEvents", instead of listeneing to direct events? So we can control the order in which they run more cleanly?

In the meantime I'll probably copy dropcursor in my app and handle the rendering more directly

You can create a plugin with props: {handleDOMEvents: {...}}
