Can't delete profile picture

I'm trying to get a better sense of how the Profile picture works in Service Portal and uploaded a random profile picture, which shows up great:

find_real_file.png

My issue is when I delete the profile pic from sys_attachment (both the entry that starts with "thumb..." and the ZZ_YYlive_profile), clear my browser cache, and refresh my page, the profile page looks like this:

find_real_file.png

At first I didn't notice anything wrong with the above screenshot, but after impersonating another user, I noticed that the font awesome user icon is missing from the large avatar, and my initials are missing from the smaller avatar in the header:

When I look inside the console for my profile, I notice that for the large avatar, there's still a sys_id associated with my profile picture even though I've deleted it completely from the sys_attachment table:

Am I missing a step in this?  If a user uploads a picture but then deletes it, how can they get rid of the sys_id that looks to still be rending a "blank" photo?
