nit: all lowercase is expected for DOM events: contentresize.

Ah, right. Actually setupEventProperty() always converts the event name to all
lowercase anyways, but there's no reason not to be lowercase already here, so
I'll change it.

+  this.setupEventProperty('resize');
   this.setupEvents();
 }
