Why do contact posters get enlarged after you select them?

Ever since iOS 26, after I choose a photo for a contact's poster (not avatar, as those are now called), the photo is enlarged and looks nothing like how I aligned it on the screen. It's certainly not supposed to be this way, I hope?

How I place it on the screen (how I hope it will stay):




How it gets after I tap on "Done":

The whole contact photo / contact poster system has been horrid for a while, but this is an additional new, undesired behavior.
