Broken syntax highlighting for generic function with... | microsoft/TypeScript-TmLanguage

Nadie ha tomado este issue todavía.

Type: Bug

Inside of a new .tsx file, create the following code:

type GenericType<T> = boolean;

const testGeneric = <T = void,>(): GenericType<T> => {
  return true;
};

const testGeneric2 = <T,>(): GenericType<T> => {
  return true;
};

Every => after the <T = void,> will be incorrectly highlighted.

Usa el fragmento de TypeScript JSX proporcionado en un archivo .tsx nuevo para reproducir el problema de resaltado. Después, inspecciona los archivos de gramática de TypeScript-TmLanguage y sigue cómo se clasifica la sintaxis de las funciones genéricas. Se considera terminado cuando los ejemplos mostrados se renderizan con el resaltado correcto en VS Code sin resaltar incorrectamente los tokens => posteriores.
