Scribe #6198 "An attached image can't be viewed large or copied back out".
Web and desktop: clicking an image in the editor opens it full size, with
Copy image (re-encoded to PNG, the one type every clipboard accepts),
Download and Close. Copy hides where the browser has no async clipboard,
such as a server reached over plain http; right-clicking the full-size
image still copies there.
Android: long-pressing an image in the editor copies it to the clipboard;
a tap still opens it full size in the phone's viewer. Opening and copying
share one hand-out that copies the file out of the blob store behind a
FileProvider URI.
