Yes, you're right.

According to the document of "load-file-rep-suffixes", the "jka-compr-load-suffixes" is used for the compressed suffixes.
So I attach a new patch, the patch will seek the "jka-compr-load-suffixes" to determine the compressed suffixes for emacs module and skip it.
Please check the attached patch for details. Thank you.
