Description

For my theme, the color settings are removed completely:

{
	"version": 2,
	"settings": {
		"color": {
			"custom": false,
			"customDuotone": false,
			"customGradient": false,
			"duotone": [],
			"gradients": [],
			"link": false,
			"palette": [],
			"text": false,
			"background": false,
			"defaultGradients": false,
			"defaultPalette": false
		}
         }
}

Nevertheless, the cover block displays the color setting for the overlay color. But clicking on it returns an empty popover, since there is no color. So if there is no color, the color setting for the cover overlay should be omitted completely.

Step-by-step reproduction instructions

1. Use the theme.json above.
2. Create a new post and add a cover block.
3. Add an image to the cover block.
4. See color settings of the cover overlay.
