Description

Step-by-step reproduction instructions

1. Add this to your theme.json

			"core/search": {
				"border": {
					"color": "var(--wp--preset--color--orange)",
					"style": "solid",
					"width": "2px"
				},

2. Notice that the search block looks like this:

The border should only apply to the input.

This also happens when you select colors in the site editor Styles sidebar. It affects the form. While if you use the setting in the block it affects the button.
