Don't think this would be the correct fix. HTTP compression https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Encoding is supposed to be used for compress-at-server-decompress-at-client to preserve network bandwidth. It could be used for any file.

If the original media is already encoded (e.g., as a .zip file), this information is not included in the Content-Encoding header.

When .gz files are served up by a server with a Content-Encoding gzip header set they should be double-compressed.

I would be curious to know as to whether the bitbucket mirror of the source issue is really hosting the gz files.
