Description

[c/stdio/sprintf] %% consumes an extra arg

When trying to use %% in sprintf to represent a % sign, it consumes an extra value from ...args.

The following examples will explain it better:

• const str = sprintf('%d%%%d.', 1, 2);
  console.log(str);

  Output: 1%0.

• const str = sprintf('%s is a %d%% %s %s.', 'Param', 90, 'good', 'boy');
  console.log(str);

  Output: Param is a 90% boy undefined.

If approved, I would like to work on this issue.
