I checked this problem for a while, This problem seems to be reproduced in CodeMirror(v5).
When tested on the CodeMirror V6 demo page, the problem seems to have been corrected. (https://codemirror.net/6/)
However, since v6 is still in the beta phase, I think we can proceed with the version-up later.

I share the relevant information for reference. ☺️

Could i try this issue?

I tried it but SimpleMDE has a strong dependence on Codemirror 5, so I think it will be a large task if we migrate Codemirror 5 to 6.
