GitMate.io thinks possibly related issues are #1357 (Allow create but not view when sharing), #5634 (Allow associating tags in gallery (tile) view and in the image fullscreen view), #2731 (Switching from gallery view to list view not possible), #3504 (showNotification closes Gallery view (probably others too)), and #1027 (Allow admin to view used quota for all users).
