[issue report] Issue on composition with a selection cross paragraph

I ran into an issue when input some chinese with a selection across paragraph. The gif demo was on the official site. reproduce step is simple.

  1. insert two paragraph 12 as the 1st, and 34 the 2nd.
  2. select the 2 and 3 characters
  3. input chinese(just press “j”) (I guess any IME composition could reproduce not tried other yet)
  4. the j remains in the beginning when I press the space key (composition end)

the gif as followed: 2022-04-07 at 00.00

Possibly a dupe of this post brought up recently?

yes, exactly the same issue, thanks for the info. : )
