The new policy options AutoOpenFileTypes / AutoOpenAllowedForURLs release in Ms-Edge-85-Beta seem to work only partially. they prevent the Open FIle (File Click) popup but they don't prevent the download confirmation popup ("Keep" button), as opposed to Chrome who introduced also these options but they prevent all the File Download/Open pop-ups in Chrome. This looks a bug in MS-Edge as the goal of these options is to prevent the pop-ups on File Download/Open.
I there a plan to fix this.
Otherwise, is there another option to prevent the download confirmation popup ("Keep" button)?
