Please add an option to mark/report an email as junk from the online inbox without opening it.

Everybody who knows anything about email knows that loading the remote content in an email is used to fingerprint you, and improve your position on spam lists. When I'm marking an email as junk, I very much do not want to open the images in it, and yet I still need to mark it as junk. Please fix this. It's incredibly basic and no one else has this issue.
