Bug description or feature request:

I write a component, and use tooltip in my component.
I need to let tooltip wider, and not hidden by other DOM.
So I use container="body", then tooltip is no longer hidden by other DOM.
But its width setting in customClass does not work (the default tooltip style is applied, but customClass's css does not work).
I guess I did a wrong usage of customClass. Can anyone knows?

You have a typo in a binding name conyainerClass="customClass", correct one in containerClass="customClass". Also you haven't used /deep/ for .customClass in your stylesheet.
