Styling of blocks

I try the WP Plugin and would like to suggest a feature. Maybe it is already on the way with the (soon?) coming FSE support?
When I create a block containing eg a button, it shows as standard (ugly grey). I use the 2023 theme and FSE. It is “the future”, so I think Pinegrow should move in same direction. It would be nice to have the possibility to implement the theme css and build blocks with current active theme styling. If I add a button, it could use the style like in the Gutenberg builder.
I added “wp-element-button” to the button and it appeared with correct styling in the builder, but not in Pinegrow, unfortunately. Of course fonts and other styles should be included.
Is this already implemented and I miss something oder is it coming soon?
