Hmm, but does it actually **await** the return value? I'm not a ext.js
expert but I don't think it is. Anyways it's fine because js promises
are executed eagerly + promise returned directly.

What do you think about adding this to the commit message:
Making the handler functions async is not a problem, because
promises in js are executed eagerly (not lazily) and nothing
depends/waits on the result of this handler.
