Describe the bug
Required bubble that appears when marking an array field as required warns of two errors instead of one.

To Reproduce
Use an empty object for data, use no uischema (autogenerated) and use the following schema object as an example:
schema: { properties: { test: { type: "array", items: { type: "object", properties: { "test1": { label: "test1", type: "string" }, "test2": { label: "test2", type: "string" }, "test3": { label: "test3", type: "string" } } } } }, required: ["test"], type: "object" }

Expected behavior
I expect there to be a bubble with a single error instead of 2.
