Specific element is copied and inserted strangely.

Summary

Thank you so much for making a wonderful library. I would like to use this library for my service. However if it is not English, there seems to be problem when using the positioner extension and entering key on the first line.

I think it will happen not only in Korean but also in other languages.

Steps to reproduce

Using positioner extension, when entering Korean on the next line of remirror-positioner-widget, the next element is copied and inserted.
I attached a video for the details.
