Button: Style variation name is different in the toolbar vs. the inspector

[richtabor]

I noticed the button block’s style variation is named “Default” in the inspector (which I consider the primary method for applying variations) and “Fill” in the block toolbar.

These should be consistent. But I’m also curious if style variations should persist in both locations anyhow #54986.

Good find.

This becomes even more confusing if a plugin or theme registers a style and sets that as the default with
isDefault: true

To test, I added this to functions.php in Twenty Twenty-Four:

		register_block_style(
			'core/button',
			array(
				'name'         => 'test',
				'label'        => __( 'test style', 'twentytwentyfour' ),
				'inline_style' => "",
				'is_default'   => true,
			)
		);

The UI shows two button styles named default:

I think the label is wrong though, block variations are the row/stack, columns and query loop variations.
