- launch the iOS Discourse app
- find a forum post with an image
- scroll the page a little so the browser navigation buttons vanish
- tap the image to expand it
- tap the “download” link under the image
- long press to save the image
Observe: From here, there is no way to go backward or exit the forum. It is necessary to force quit the app
Expected: Tapping or scrolling the image should present a way to escape from the image view.
