This is not the way to support rich text. Consider checking out how title.textStyle does. And there is no good reason here using ts-ignore to ignore the typing problems.

This should be a new feature instead of a bug fixing because there isn't doc for rich now and you need to check "The document should be updated later".

Also, you should include test cases as according to the wiki.
