This is due to malformed upstream data in BCD. There's a PR open to clean it up, but it's been in progress for months and shows little sign of progress: mdn/browser-compat-data#26624

I've opened a PR to provide stopgap improvements for the status on this feature in mdn/browser-compat-data#28408.

Thanks for reporting this, @una!

Fixed with #3516. This will appear in the next release, which should happen today.
