Description
With the following code:
interface Foo extends FirstClass, SecondClass {
test: string;
}
I would expect FirstClass and SecondClass to be highlighted the same way, but only FirstClass is highlighted as a class-name. This is the result:
This syntax is documented under "Extending Types" in the typescript handbook.

Research direction
Start with Prism's TypeScript/TSX grammar and reproduce the example in the linked Test Drive. Compare highlighting for the first and subsequent types in the interface's extends list; done means all extended types receive the same class-name highlighting without regressing the shown syntax.
