The source link of the photo is displayed in the menu, then the options.
"about:blank" is displayed, then the options.

I was just about to report this. Note that Fennec does even better than the source - it shows the alt text. This can be seen on xkcd.com comics.
Alt text should only be displayed when the image fails to load. Displaying title text is #580.
Is this still an issue? I can't reproduce on the latest A-C and Fenix versions.
I'll add QA needed label to retest
It is no longer reproducible on RC 2.0.0-rc.2. Tested with Samsung Galaxy Tab S3 (Android 8), and OnePlus 5T (Android 9).
