When I try to delete text in a node that contains an input element by hitting Backspace it ends up deleting text after the node. Playground does seem to have this issue too with Poll node.

Lexical version: 0.6.5

Steps To Reproduce

1. Go to Lexical Playground
2. Insert a Poll node and type in some poll options
3. Put the cursor on the text after the inserted node
4. Put the cursor back in one of the input options
5. Try to delete characters with Backspace

The current behavior

Characters are being deleted in text before or after the node

The expected behavior

Characters are being deleted in the input element
