core/comment-date doesn't obey font-size settings

[pbking]

Description

The comment-date block is ALWAYS 'small' size and cannot be customized either via Global Styles or block attributes.

Step-by-step reproduction instructions

Tested with Empty Theme.

Add the following block to a page:

<!-- wp:comments-query-loop -->
<div class="wp-block-comments-query-loop">
<!-- wp:comment-template -->

<!-- wp:comment-date {"style":{"typography":{"fontSize":"4px"}}} /-->

<!-- /wp:comment-template -->
</div>
<!-- /wp:comments-query-loop -->

Render a page that has at least one comment.

Note that the comment-date is rendered with BOTH the font size set to 4px (via style attribute) and --wp--preset--font-size-small. But since the small font size is !important it always wins. The block has the has-small-font-size class which it shouldn't have.

This was also tested with the block like this:

<!-- wp:comment-date /-->

as well as theme.json settings like this:

{
	"styles": {
		"blocks": {
			"core/comment-date": {
				"typography": {
					"fontSize": "4px"
				}
			}
...

The result was the same.

Looks like this will be fixed via #41627 which is already about to land. :)
