Description
When I have the discriminator property explicitly listed on the components that are under a oneOf, it disappears when mapping is used under discriminator.
For example with the following document, the example is
{
"prop2": "string"
}but with mapping removed it changes into
{
"prop2": "string",
"type": "string"
