Thanks to @42tte for finding the inconsistencies between vue-autosuggest and the wai-aria spec by moving some attributes into the surrounding wrapper!
Migrating to 2.2.0: It should not affect any functionality (minor release), but you might be mindful of where the role="combox" is and also how the aria-controls are located if you relied on those for any reason for styling, though that is not recommended since there are plenty of classes to target.
Welcome @42tte as a new contributor!
