This is in the latest Illustrator. And All formats do it.

Can you run through your exact workflow? You say 'all formats' do this; please give one example:
1. What is in the file?
2. What exactly do you do to save/export?
3. What file format do you use?
4. What do you then do with the file in order to view it?
