Extended enum values are not recognized

I really appreciate this plugin and I’m not trying to be a bother with opening issues left and right, but I did notice another thing about enums.

Version and Environment Details

Operation system: macOS Mojave 10.14.6

IDE name and version: Webstorm 2019.2.3

Plugin version: 2.2.0

Expected Behaviour

When extending an enum type by extend enum MyEnum {EXTRA_VALUE}, the plugin should correctly recognize EXTRA_VALUE as a value of MyEnum.

Actual Behaviour

The plugin displays an error for every value which is not present in the original definition of the enum.

enum AuthRoles {
  USER

extend enum AuthRoles {

  CURRENT_USER
  OR
  AND
  NOT
}

type Query {
  getUser(id: ID!): User @auth(if: [ADMIN OR CREW OR CURRENT_USER])
}
