Repro Code

// Fails with "'args' is already declared in the upper scope on line 2 column 65."functiontestFail1<Fextends(...args:any[])=>any>(fn:F, ...args:any[]){return[fn,args];}

ESLint Config

module.exports={parser:"@typescript-eslint/parser",rules:{"no-shadow":"off","@typescript-eslint/no-shadow":"error"},};

tsconfig

{"compilerOptions": {  }}

Expected Result

I expect no errors.

Actual Result

I get the error'args' is already declared in the upper scope on line 2 column 65.

Additional Info

The argument name in the generic has no effect on the rest of the code. Granted, it's a bit confusing to read, because the twoargs are completely unrelated, but there's no shadowing going on here.
