Drop zone provider: option to avoid wrapper element #27079

Description

Currently the drop zone provider has two purposes:

  • Provides context used to communicate between drop zones and drop/dragover handlers.
  • Adds event listeners for drop/dragover on an element it provides.

The element is not strictly necessary, so the latter purpose could be isolated behaviour in a hook, while the former could be purely a context provider.

Why? While it's always good to separate pieces of functionality and remove unnecessary div wrappers, this separation makes it also easier to implement iframing the editor content. With the drop behaviour separated, we can call it within the iframe on the body element.

I marked the new provider and hook unstable for now. I have some more thoughts on how we could potentially avoid the context and behaviour hook altogether if we manage to built it into the drop zones themselves. This requires some time to explore though.

How has this been tested?

Hey @ellatrix - this PR seems to have caused some regressions about drag n drop like here: #28512.

The problem is that when you have opened the media library and drag the image, if you drop it in a place that below the modal is another drop zone (even if it's not visible due to the modal) it will upload to both drop zones.

I tried reverting this PR (had to change two lines manually, but that was quite straight-forward), but the problem still seems to persist for me 😕 (Experimental PR here: #29516)

Weird 🤔 - git bisected in a wrong way :) ?

I think @ellatrix will have better input for this... This line here is the one that enables both drop zones to be active, even if they are not visible.

I'm not sure how drag and drop into the media library and content are related?
