List block: copy/paste individual block results in inconsistent experience

[annezazu]

If you try to copy/paste individual items, it's wildly inconsistent whether you can get the block to actually copy and, when pasting, it often pastes just as a paragraph rather than a list block:

• It's hard to get it to truly copy an individual list block.
• When pasting, most of the time it pastes an individual item as a paragraph.
• Sometimes when copying, it then won't have anything to paste

Here's a video demoing all of this with 6.3 RC1:

This is similar to #48254, but unfortunately not fixed by that PR because the list block uses a div element for rich text, so it doesn't copy over the tag. We'd need #41628 for that. Alternatively, we somehow need to allow the paste even's data transfer to be manipulated by the block that hosts RichText. 🤔

After a review by core editor triage leads and core editor tech leads, this has been removed from the board for 6.5 consideration.

When I use Cmd+A to select all list items, then copy, then attempt to paste, nothing is pasted. Pasting single list items, or some (but not all) list items, does work. See screenrecording below from https://wordpress.org/gutenberg/ on Firefox (MacOS):

This is a blocker for us on Tumblr, where we're trying to upgrade to List block v2.

If this is a distinctly different bug from this issue, let me know and I can open a separate ticket.

@ellatrix can you look into the above?

[annezazu]

To be safe, I've opened this issue to cover your use case @17cliu #59381 and have added it to the 6.5 board as I can replicate with 6.5 beta 2. Thank you for reporting!

Thank you @annezazu !
