Also please feel free to use 0.8 for the time being as it's not inferior in terms of features

OK, I've done a bit of investigation. IE9 and IE10 works just fine, the problem here is that these two should use HTMLUnknownElement as default prototype, instead of HTMLElement which is inconsistent with other browsers behavior, including IE11.
Long story short, I need to feature detect this somehow and try to fix it, if possible, but that would make them inconsistent anyway so I'll think about it.
Meanwhile I can assure you that nothing is actually broken and the reason contractor was red is that there was no constructor test before in 0.8.0
Feel free to use 0.1.x in those browsers too as you can see now the test is green.

My apologies for not researching this more thoroughly. I have a better idea of what's happening now.
Beggining in 0.1.0 - only in IE 9 and 10 - you cannot include your document.registerElement calls in the <head> (unless you wrap them in a window.onload, or similar). This was possible in 0.0.8.
You can duplicate the issue using the "Usage Example" in the readme.
It's not too hard to work around, but it doesn't match native behavior, so it might be worth documenting...

would you be so kind to double verify that version 0.1.2 is working properly for you ? Thanks

It is working. That was fast! Thank you very much - this is a great polyfill!

I might find a better/more performant way to trigger that check at runtime via DOMContentLoaded instead of readystatechange that might fire multiple times but it was more important to fix this so I hope you won't mind closing this ticket if you think this problem is solved.
I will solve the other constructor problem a part thought, but in another ticket and when I'll be back from this little vacation :-)
Have a great weekend.
