Description

If I want to disable all border settings using theme.json, according to the documentation, I should use:

{
	"version": 2,
	"settings": {
		"border": {
			"color": false,
			"radius": false,
			"style": false,
			"width": false
		}
	}
}

This correctly disables the border settings for some blocks, like the group.
But it does not disable any border settings for the pullquote block.

If I instead use :

{
	"version": 2,
	"settings": {
		"border": {
			"color": false,
			"radius": false,
			"style": false,
			"width": false
		},
		"blocks": {
			"core/pullquote": {
				"border": {
					"color": false,
					"radius": false,
					"style": false,
					"width": false
				}
			}
		}
	}
}

Then the border setting is hidden also for the pullquote block.

Step-by-step reproduction instructions

Open the theme.json of any block theme, delete everything in the file, and copy paste the first example from the issue.
Activate the theme.
Open the block editor or site editor and add a pullquote block.
Confirm that the block still has border options.
Repeat the steps with the second code example, and confirm that the block no longer has a border options.
