Bug: Pasting emoji at the end clears editor (MaxLength)

[im-adithya]

#2296 (comment)

lexical-.4.mp4

Lexical version: Latest

Steps To Reproduce

1. Type any random 30 characters
2. Copy this emoji 💏 or any other emoji of length 2 (occupying a length of 2, otherwise this emoji is actually of length 11 as shown by '💏'.length which also can be an error if lexical is supposed to treat this as an 11-length emoji, but a....a💏 (28 as) works fine in MaxLength)
3. Remove a character and paste the emoji at the end (and ONLY at the end, otherwise the behavior is proper)

The current behavior

The entire editor gets cleared and the Block Format dropdown disappears! (I've found out that it is because the blockType of editor gets changed to root after being cleared)

The expected behavior

It shouldn't allow the emoji

Note

I would like to work on this after getting to know a bit more about emoji guidelines as that would help in a better understanding of the functionality!
