Using with Golden Layout

[klongmitre]

I'm trying to use this component with Golden-Layout, but was running into an error where contentWindow was not yet set when the vue-friendly-iframe component was mounted.

In setIframeUrl function, I was able to add...

if (this.iframeEl.contentWindow === null) {
        setTimeout(this.setIframeUrl, 10)
        return
}

...which seems to get it to load, but this seems like a hack (or maybe it's not). Any thoughts on how to do this more gracefully?
