I found users having various bugs related to saving images in the gallery when trying to right-click or hold-tap on an image in an open gallery.

Seems like windows 10 browsers — right clicking causes the gallery to close instead of giving the user the option to save the image.

On IOS Safari — the user can hold-tap on the image and never get an option to save the image.

On Android Chrome and all the MacOS browsers I've tested it with, I am still able to save the image on a right-click or hold-tap.
