Hi !

First of all thank you for this package it does an amazing job!

The problem I encounter is that when I enter a long text in an "emoji:RichTextTbox", it takes a long time to appear, whereas on a classic RichTextBox, everything is ok. I can't find the source of the problem for days

I made you a very simple example so that you can see it.

Running into this same issue. Inserting lots of text into the RichTextBox (with no emojis, just text) is freezing the application for long periods of time. Regular RichTextBox runs without issue.
