iOS 13 Photos app - what does this icon mean?

[Falcon_64]

Apparently my Google-fu needs some work - was going through some photos I took with iPhone 11 Pro Max and iOS 13 (not sure which update if it matters). Some of them have an icon I have so far been totally unable to identify - anyone know what this icon means, the one circled just under the work Edit?

Thanks

Thats the photo capture outside the frame icon if im not mistaken. I have that option turn on since day 1 but its weird that only few of my photos that I can edit using that
