I noticed that, if logged in incognito mode, I didn’t have this problem. Back using my standard Chrome profile, I ensured all browser extensions were disabled, and I still had the problem. Then I just cleared all browser cache and cookies, and the problem went away. So I couldn’t pinpoint what it was in my browser settings that caused this, but the problem is resolved now.
(Matt, if you see a support case that I’m copied on that reports the same, you can consider it resolved!)
