Description

I try to register a BlockVariation like so:

registerBlockVariation( 'core/group', {
	name: 'card',
	title: 'Karte',
	description: 'Style Group as a Card',
	attributes: {
		anchor: 'is-card',
	},
	isActive: [ 'anchor' ],
} );

I can insert the variation in the editor, but it is not active after I insert it.

My guess was that there might be a conflict with the default group:variation.

So i try to give a stronger isActive specification, but it does not work for me.

registerBlockVariation( 'core/group', {
	name: 'card',
	title: 'Card' ,
	description:  'Style Group as a Card',
	attributes: { layout: { type: 'constrained', className: 'is-card' } },
	isActive: ( blockAttributes ) =>
		blockAttributes.className === 'is-card' &&
		( ! blockAttributes.layout ||
			! blockAttributes.layout?.type ||
			blockAttributes.layout?.type === 'default' ||
			blockAttributes.layout?.type === 'constrained' ),
} );

Do i miss something?
