Description

The new block variations for the group block generate inline CSS, but the lack of a CSS class name (e.g. wp-block-group--stacked or wp-block-group--row) makes it impossible to target these elements using theme/plugin CSS.

Step-by-step reproduction instructions

Apply a row or stack layout to the group block.
