I didn't catch this when this class was initially added but it's probably not a good idea to set the warning message in the constructor.
We should just add a member function which sets the warning message.
Then we can simply forward it to this.setButtonTitle, which would avoid this problem without having to create a LazilyEvaluatedFunction.

We usually define these after render().

It's a bit strange to call setButtonTitle on WarningIcon.
I think we should add a method like setWarning on WarningIcon itself, which is a trivial forwarding to setButtonTitle.
