theme.json schema: Incorrect validation on filter, outline, shadow

[t-hamano]

Description

Related to:

• added outline support for blocks via theme.json #43526
• add box-shadow support for blocks via theme.json #41972
• Add schema support for styles.filter.duotone #41920

JSON schema validation does not work correctly for filter, outline, and shadow, which are style supports recently added to theme.json.

These properties are considered invalid properties after entry, even though they are displayed as a list of input candidates by the code editor. This would mean that the JSON schema definitions are inconsistent.

This problem occurs for the following properties:

• styles.outline
• styles.shadow
• styles.elements.button.:active.outline
• styles.elements.button.:focus.outline
• styles.elements.button.:hover.outline
• styles.blocks.{blockName}.filter
• styles.blocks.{blockName}.outline
• styles.blocks.{blockName}.shadow

I will update the schema appropriately according to the expected specifications.

Step-by-step reproduction instructions

• Save the following template as a JSON file:

{
	"$schema": "https://schemas.wp.org/trunk/theme.json",
	"version": 2,
	"styles": {
	}
}

• Enter the properties according to the list above.
• Confirm that the property is considered invalid after entry, even though it is displayed as a candidate.

Screenshots, screen recording, code snippet

The following is a list of all possible properties with filter, outline, and shadow added.
As you can see, some properties are considered invalid.
