Photoshop CC suddenly Cropping Smart Objects or other fills to Canvas when moving them around

Hello All,

I'm posting this on behalf of another designer I work with.  I have not experienced this issue however they have suddenly come across this problem.  We're both running Photoshop CC 23.5.1

Delete Cropped Pixels is unselected, nothing else is selected (no marching ants), and Reveal All will not show anything.  PS is automatically cropping things to the canvas bounds, so if he moves a logo around and half of it leaves the canvas it will be automatically cropped to the border, and the logo will be clipped in half if he moves it back. 

Could he have accidentally enabled some setting that does this?  

Thanks.
