Subject: [PATCH] Update the `FontLoader.bind` method to avoid explicitly
 returning `undefined`

The only reason for the `return undefined;` lines was to appease the ESLint `consistent-return` rule, but that's not actually necessary if you make use of the fact that the method is `async` and that we can thus await the Promise rather than returning it.
