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"
}
