Is there a separate issue for the Rounded button not being rounded?

[andersnoren]

The theme only includes the "Fill" (default) and "Outline" button styles, so it doesn't have a rounded style. The style also isn't called rounded in the block editor – the default block styles just styles "Standard" as rounded.

I see. I always thought it odd that the default required a style to achieve it.
