User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36

Steps to reproduce:

1. Create a SVG element with <image> with valid href using 'implementation.createHTMLDocument'.
2. Get the <image> and paste it inside main document with SVG element.
3. Add two listeners to the image: 'load' and 'error' 
All this steps are done here https://codepen.io/anon/pen/ajoEJz?editors=1111 
Take a look at console

Issue is reproduced with versions 61 and 63 (nightly)


Actual results:

'error' event is fired two times, then 'loaded' event is fired


Expected results:

Only 'loaded' event is fired

I also tried to create svg and image using 'new DOMParser().parseFromString', but result is the same:
