Make .wp-block-post stylable via theme.json

[ClarusDignus]

Problem

I can style various aspects of the Query Loop block via theme.json.

E.g. core/post-template styles .wp-block-post-template, core/post-title styles .wp-block-post-title, etc.

"blocks": {
	"core/post-template": {
		"border": {
			"style": "solid",
			"width": "1px",
			"color": "#000"
		}
	},
	"core/post-title": {
		"border": {
			"style": "solid",
			"width": "1px",
			"color": "#000"
		}
	}
}

However, core/post doesn't style .wp-block-post.

"blocks": {
	"core/post": {
		"border": {
			"style": "solid",
			"width": "1px",
			"color": "#000"
		}
	}
}

.wp-block-post is the container of each post outputted by the Query Loop block, i.e., it contains each post's title, featured image, date, excerpt, etc.

Proposed Solution

Please make .wp-block-post stylable via theme.json like the elements it's within and elements within it.

Currently, I'm limited to styling .wp-block-template via style.css. One of the downsides of this is that the style doesn't apply in the editor.

core/post isn't a block in the sense that it can be selected and edited via the editor.

This class can now be styled in theme.json with the custom CSS option.
Does that solve the issue?
