Yes, that did fix it! I'm surprised this is necessary, though. Can you offer an explanation?

Also, using fixedSize causes the text not to wrap or truncate, which makes sense given what fixedSize does, but isn't quite what I'm hoping to achieve. (It's an improvement, to be sure.)

Is there a SwiftUI or UIKit component that will render block styles like code blocks, block quotes and tables?

Whoops. Thank you!

I knew I was doing something dumb, thank you!

Ahh, thank you! I knew there had to be a new modifier to match the UIListContentConfiguration.prominentInsetGroupedHeader() from UIKit.

I've not tried this, but I imagine the new SwiftUI @FocusState API (watchOS 8 only, of course) should hopefully help with this.
