Comment 1 Justin Zobel 2020-11-13 05:41:42 UTC 
I've just tested this on kate from git master by copying the entire first comment in by drag and drop and I cannot reproduce this issue.

Does this happen for text from all other applications or just MATLAB?

Can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved. I'm setting status to "needsinfo" pending your response, please change back to "reported" or "resolved" when you respond, thanks.
Comment 2 opensuse.lietuviu.kalba 2020-11-23 07:19:36 UTC 
Now I can not reproduce this bug in openSUSE Leap 15.2 today with Kate 20.04.2.
I guess there were some JAVA issues related to MATLAB previously...
