Delete all with minItems

[Cosmocat]

Hello,

Delete all has unwanted effect when you have complex object as an array item:

{
"title": "demos",
"type": "array",
"minItems": 3,
"items": {
"type": "object",
"properties": {
"prop1":{ "type": "string" },
"prop2":{ "type": "string" }
}
}
}

Adding item and then delete all would remove properties for all items in array including "required" minItems.
