IE 10 Error: Invalid Argument on insertBefore

[caneruguz]

I had this "Invalid Argument" error on otherwise working code:

After some digging it looks like IE needs a valid DOM argument for the second argument of insertBefore. I'm not sure if in Mithril this always has to be a valid argument and I'm somehow making a mistake in my code. However changing the line from this:

parentElement.insertBefore(dummy, parentElement.childNodes[change.index])

to this, solved the problem:

parentElement.insertBefore(dummy, parentElement.childNodes[change.index] || null)

I'm using Mithril 0.1.22
