Custom expression properties do not work when they are added to a choice item definition

[andrewtelnov]

If you define this expression property, then it will not work property for select base questions:

import { Serializer } from "survey-core";

  Serializer.addProperty("itemvalue", {
    name: "customExp:expression",
    onExecuteExpression: (obj, res) => {
      obj.setPropertyValue("customVal", res);
    }
  });

onExecuteExpression function is not executed.
