Support drag and drop between windows

[FezVrasta]

Is your feature request related to a problem? Please describe.

HTML5 drag-and-drop supports interactions between windows. This issue is to ask to support it on the react-dnd HTML5 backend too.

Same as #1533

Describe the solution you'd like

Drag and drop should work across windows.

Describe alternatives you've considered

I looked for other libraries that support this but I couldn't find any.

Additional context

Second this, since it's one of the things that makes HTML5 drag and drop special. I would add that a very nice to have would be cross origin support (possibly through postMessages?) for e.g. embedded iFrames.

I'm not a maintainer but given the architecture of the lib (redux) I have a hard time seeing how this could be achieved. Perhaps using redux-persist on the state managed by the library and persisting on localStorage, but there is no way to achieve updates synchronously.

What do you mean? Is this library built using Redux?

Hello! Have you find a solution or workaround for this?

[FezVrasta]

No, I implemented my own solution/hook at the end

I created use-dnd to allow this if anyone is interested in a pre-built solution. Unfortunately it's HTML5 DND-only (so no touch support) but if that's all you need then it hopefully shouldn't be too hard to migrate (or maybe combine both libraries together to get the best of both worlds, though I haven't tried doing that myself). Warning that it's mostly untested except for the specific scenarios I needed, so I can't promise as much reliability as react-dnd can. 😅
