I can't replicate on mine. If this is due to nested styles, I think you are behind on your software updates :). But also, maybe I need to hold off a bit longer before moving to nested styles.
According to a forum post [1], e.g. iPad Mini 4 was discontinued March 2019 and is stuck on iOS 15, which doesn't support nested styles. Perhaps the issue is that people want to continue using old tablet devices that are no longer getting OS updates?
