IE11: this.get('closeSrc') is undefined

[palsingh]

In IE11, this.get('closeSrc') initiates a request to /undefined.
Setting it in config while creating new instance of infobubble doesn't make any difference.

The problem is that setValues is called after buildDom_ in the constructor. Reversing the order doesn't work either, because it fires change callbacks for properties where the DOM is expected to already exist.

Adding:

  this.set('closeSrc', options['closeSrc']);

before the buildDom_ call in the ctor gets rid of the problem, but it seems a bit hacky.

This is reproducible on Firefox 52.0.2 (latest) also and sometimes is responsible for crashing our sessions. Are there any plans to fix it?
