Description

With the aspect ratio now available for the Gallery block, it should be controllable via theme.json for this core block according to the theme.json schema.

It is my understanding:

• "aspectRatio": true enables the feature
• "defaultAspectRatios": false disables the default list
• "aspectRatios" [ ] provides a custom list of aspect ratios.

However when I try to enable the feature and provide a shortened list of aspect ratios it doesn't display in the settings tab of the gallery block.

Step-by-step reproduction instructions

• Add below code snippet to your theme.json's settings section on your test site.
• Add a gallery block to a post or page
• Open the block sidebar on the settings tab
• The aspect ratio drop-down list doesn't appear.

"blocks":{
	"core/gallery":{
		"dimensions":{
			"defaultAspectRatios":false,
			"aspectRatio": true,
			"aspectRatios": [
						{
				"name": "Square - 1:1",
				"slug": "square",
				"ratio": "1"
				},
				{
				"name": "Wide - 16:9",
				"slug": "16-9",
				"ratio": "16/9"
				},
				{
				"name": "Tall - 9:16",
				"slug": "9-16",
				"ratio": "9/16"
				}
			]
		}			
	}
}
