How to jump to the definition of a template string type in VSCode?

• VS Code Version: 1.82.2
• OS Version: win11

I’m using TypeScript 5.2.2 and VSCode 1.82.2, and I have a problem with jumping to the definition of a template string type.

Here is my code:

type Test<T extends object> = {
  [K in keyof T]: () => void
} & {
  [K in keyof T as `${string & K}Sync`]: () => void
}

const a = {
  getValue() {}
}

const b = {} as Test<typeof a>

b.getValueSync()
b.getValue()

I want to jump to the definition of the Test type, but when I press F12 on getValueSync, nothing happens. However, when I press F12 on getValue, it works fine and jumps to the definition of a.getValue.

I wonder if this is a bug or a limitation of VSCode or TypeScript, and how can I solve it. Any help or suggestion would be appreciated. Thank you.

Riproduci il comportamento F12 segnalato in TypeScript 5.2.2 e VS Code 1.82.2 usando l’esempio di tipo mappato tramite template literal presente nell’issue. Non viene indicato alcun file del repository né alcun test; traccia la richiesta di definizione del language service per getValueSync, quindi verifica il comportamento rispetto a getValue e documenta o testa il risultato atteso.
