This issue affects e.g. express used with new route handlers which are required to be non-async in their TS typings. I think in case of variadic arguments, the plugin verifies just the 1st argument and, if it's okay, doesn't even check the rest of the arguments.

• I have tried restarting my IDE and the issue persists.
• I have updated to the latest version of the packages.
• I have read the FAQ and my problem is not listed.

Repro

{
  "rules": {
     "@typescript-eslint/no-misused-promises": "error",
  }
}

function get2(_h1: () => void, _h2: () => void) {}

function get(..._handlers: Array<() => void>) {}

get2(
  () => {},
  async () => {} // <-- fails, which is what we want
);

get(
  () => {},
  async () => {}  // <-- this must fail too, but it does not
);

Expected Result

Both get() and get2() calls must raise an eslint error.

Actual Result

Only get2() is treated as incorrect, and get() is fine - although it should fail too:
