Hello

when using the TeX input method with

GNU Emacs 28.0.90 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.22.30, cairo version 1.15.10) of 2021-12-08
    
I'm getting for "ConsonantUnderscoreConsontant" examples this

  eₑ mₘ  sₛ.

But for the MingGW build it looks strange, please consider the attached
images. (The image was done with 28.0.69, but it looks strange for
28.0.90 as well.)
