[iPadOS beta 1-2] Safari shows Twitter favicon for latest topics on MPU

For some reason the latest topics from MPU, i.e., this url MPU Talk is given a Twitter favicon in Safari. This is the only page showing this. Clearing all data in Safari doesn’t do anything.

Has anyone else observed this?

I get this kind of favicon mixup with a few of the sites I read frequently in Safari. Hoping it will eventually be fixed.
