As discussed on Slack yesterday, this will add a title to all clickable components.
I modified the play toggle test to also check for this, as this was the only test that seemed to test for this already.
Because controlText is already called in createEl I had to pass the element to set the title on to the function.
This sets the title HTML attribute on all clickable components when setting controlText_ initially or changing it using controlText(...).
Add title to all clickable components
is it possible that this.el() will end up returning nothing?
Only during the first call, because that is made from createEl, at which time this.el() does not eixst yet. Afterwards it should always exist, right?
