Description slatejs can't working correctly with CJK IME on Firefox. May output duplicated and crash on Firefox

Steps To reproduce the behavior:

2. Select all default text, and delete it.
3. Typing any CJK text
4. CJK text be duplicated.
5. Try to delete duplicated text (i.e. any operation that delete the dom that contain duplicated text)

Expectation working correctly.

Environment

• Slate Version: latest (?)
• Operating System: MacOS
• Browser: Firefox 100.0.2

Context Error message:

Cannot resolve a DOM point from Slate point: {"path":[0,0],"offset":7}

Is there exists some issue when slate updating DOM data ?

On Chrome 100, when typing CJK text at end of hyperlink, then CJK text will be duplicated or break IME composition during typing, and crash randomly.
