What?

Currently when copying one or multiple list items (or all), they are copied with the list wrapper.

Why?

List items must be copied with a wrapper to be valid HTML.
Currently copied list items can't be pasted outside of lists.

How?

Signals to the copy handler that a wrapper block needs to be created by setting extra clipboard data.

Testing Instructions

Enable experimental list v2.
Create a list with list items. Select a single or a few list items. Copy them and paste them in an empty paragraph. What is pasted should be a list (including the correct attributes).

This tests great! Tried the instructions also cross editors (GDoc, Pages, Plaintext) and works as expected.

I like this meta info in the clipboard :)

I've found a couple of glitches with nested list (they can be looked at separately from this PR).

  • copy a single item just before a nested list (it seems a selection issue according to the flashing that happens upon copying):

  • copy partial list items across different nesting levels: it seems that the wrapper doesn't get attached in this case

Not sure what you'd expect here. The nested items are, well, nested to the item you're copying, so it seems appropriate?

For the second item, it seems like the selection is wrong (based on the position of the toolbar).
The problem here lies a bit deeper. We're trying to set a multi selection to starts in a child and ends in a parent that contains the child. At the moment, multi selections across different root blocks are not even allowed. So we need to make some adjustments to the action/reducer.

My expectation was that only the parent was copied. I can see why that happens (the nested are child of the item I selected) and it makes sense within the block editor interaction model (selects whole blocks). Though the behavior is different from what typical editors do (docs, office).
