"Spacebar deletes photos in Mac OS Photos.app - what kind of feature is this?: When I use spacebar to preview a photo stream in Photos.app, and then hit spacebar a second time when viewing the photo, it deletes the photo without prompting. The behavior is similar in recent photos, except that I get a delete confirmation dialog. Is this normal? Is it possible to modify this behavior so that spacebar previews and returns and stops deleting my photos?"

No. This is not Normal.
So, two thoughts:
A. Reset the SMC and your NVRAM:
Sometimes when changes are made to the system(i.e. updates), system configurations (i.e. for Keyboard) become manipulated, technically. So, reset the SMC and NVRAM. It might take upto three tries to reset both. So, be certain you have the time to perform this.
B. Report this to Apple:
- Go Here: Feedback - macOS - Apple
- Select: "Bug Report" for "Feature Type"
- Select: "Applications/Utilities" for the "Feedback Area"
- Proceed from there as necessary
