Additional context or thoughts

This may be related to the fix of the following bug: https://github.com/swagger-api/swagger-ui/issues/4291

Start the local Swagger Petstore demo and open a model such as Order while watching the browser console. Trace the warning from the Model and ModelWrapper entries in the reported stack, then verify that opening models no longer emits the invalid schema prop-type warning.
