I think we should check the name attribute and fall back to the src.  Having this would break a lot of old code, and is very avoidable.

I'm thinking something like this:
```javascript
var iframeName = $('iframe[src="'+elem+'"]');
if(iframeName.length){
  //We have the iframe, lets update the css
}else{
  //Fallback to src lookup
}
```

The other idea I had is we could pass the name or src in the message. Any thoughts?
