Rubyzip reseting file mime type headers

[6temes]

Hi,

I am using Rubyzip to edit .docx files, and I realized that the file's Mime Type gets updated every time I open it.

Before:

$ file -I my_file.docx
my_file.docx: application/vnd.openxmlformats-officedocument.wordprocessingml.document; charset=binary

After:

Zip::File.open 'my_file.docx' do |zip|
  #  Even without doing anything.
end

$ file -I my_file.docx
my_file.docx:  application/octet-stream; charset=binary

Would there be any way to specify the mime type of the original file, or just keep it as it was?

I can't reproduce this with 2.3.2 or HEAD. I am using Linux, which OS are you using?
