Hello ,
There an issue that I found out after I copy paste from Microsoft word.
If you apply a styling to a whitespace, it results with asterisk **** or ~~~~ in the markdown.

Lexical version: 0.17.0

Impact of fix

I am new to lexical, and I am having a hard time to fix the issue for a company. Is there a solution such as Markdown Transformer to add it to the array of transformers ?

export const PLAYGROUND_TRANSFORMERS: Array<Transformer> = [
  HR,
  ...ELEMENT_TRANSFORMERS,
  ...TEXT_FORMAT_TRANSFORMERS,
  ...TEXT_MATCH_TRANSFORMERS
];
