Current typescript-estree cannot parse labeled tuple types. So we should put this in /tests/misc/typescript-babel-only for now.

Sorry, but this isn't a valid isolated reproduce. If you can't provide a reproduce that doesn't involve third-party things like VS Code or CodeSandbox, that means that the problem is not on Prettier's side. Prettier formats that code with no problem: playground
