JSON Schema Conditionals - Different Behaviour Between IDEs - json

Question

I have two private IDE plugins that are generating JSON schemas to validate things. They are comprised of a bunch of definitions that are conditionally used with pattern regexs. The problem occurs in that the schema has different behaviours in IntelliJ and VS Code.
The schema is similar to below, however reduced and redacted:
{
"$schema": "http://json-schema.org/draft-07/schema",
"type": "array",
"additionalItems": true,
"definitions": {
"meat": {
"$id": "#/definitions/meat",
"type": "object",
"properties": {
"cut": {
"$id": "#/definitions/meat/cut",
"title": "cut",
"type": "string"
},
"fillet": {
"$id": "#/definitions/meat/fillet",
"title": "fillet"
},
"bones": {
"$id": "#/definitions/meat/bones",
"title": "bones",
"type": "string"
}
},
"required": [
"cut",
"fillet"
],
"additionalProperties": true
},
"fruit": {
"$id": "#/definitions/fruit",
"type": "object",
"properties": {
"pips": {
"$id": "#/definitions/fruit/pips",
"title": "pips",
"type": "string"
},
"stone": {
"$id": "#/definitions/fruit/stone",
"title": "stone"
},
"citrus": {
"$id": "#/definitions/fruit/citrus",
"title": "citrus",
"type": "string"
}
},
"required": [
"stone",
"pips"
],
"additionalProperties": true
}
},
"items": {
"$id": "#/items",
"type": "object",
"properties": {
"name": {
"$id": "#/items/name",
"type": "string",
"title": "Name"
},
"food": {
"$id": "#/items/food",
"type": "string"
}
},
"allOf": [
{
"if": {
"properties": {
"food": {
"pattern": "meat"
}
}
},
"then": {
"properties": {
"variants": {
"$ref": "#/definitions/meat"
}
}
}
},
{
"if": {
"properties": {
"food": {
"pattern": "fruit"
}
}
},
"then": {
"properties": {
"variants": {
"$ref": "#/definitions/fruit"
}
}
}
}
],
"additionalProperties": true
}
With YAML structure:
- name: orange
food: fruit
variants:
pips: true
So with food being fruit it will match, validate and suggest for that schema, and require stone and pips.
This works in VS Code. IntelliJ however, requires stone and pips correctly, however suggests keys from meat's properties.
This made me question if I have the correct implementation here - should I be using allOf, anyOf or oneOf here? I only need to match one. I also tried adding else: false, however that didn't change anything, and I still get suggestions for meat. When originally writing it, I think I found someone saying allOf will evaluate correctly as the unmatched patterns won't stop the merging of subschemas.
What I'm trying to identify is, is this an issue with my schema implementation, or a bug in IntelliJ's parsing of conditions? Or perhaps a bug in VS Code's parsing that has let me get away with faulty schemas.
