(a) Looking around me, I'm struggling to find a photo I could take that wouldn't trigger this "edge-case" – so it can't be that much of an edge-case.

(b) I'd expect them to patch this particular issue, now it's been widely-publicised, but Apple's pushed bigger defects to prod over the last few years (e.g. https://www.applevis.com/bugs/ios/when-editing-text-using-ha...). I'd be extremely surprised if this feature shipped in a properly usable state, especially given that their marketing shows that several fundamental design flaws are works-as-intended.
