Bug description

After upgrading to version 9 and adding multiple classes to disabledClass option, swiper crashed with the following error:

Uncaught DOMException: Failed to execute 'add' on 'DOMTokenList': The token provided ('foo bar') contains HTML space characters, which are not valid in tokens.
