typescript.lang: export default interface incorrectly highlighted
This is valid code. An interface can be the default export: https://www.typescriptlang.org/play?#code/KYDwDg9gTgLgBAE2AMwIYFcA28CWA7GYKNAY2DgAlhNMI4BvAKDhbgBVgBnGALjm6j4A5gG5GAXyA
However, by how GtkSourceView highlights this it looks like there's an error by how I'm reading it (note the bolder font). E.g. a default exported function does not get this kind of highlighting.
This applies to both .ts and .tsx files.
