Remove a javascript error with the Node.contains()

[tzi]

Hi!

I had a JavaScript error, when I was testing the video demo.
The Node.contains() was used with a string in arguments instead of an element.

Mainly, I have no idea why you are doing this test.
modal.focus() is called just one time, and we know that modal.activeElement is the hashElement.

Cheers,
Thomas.

Good point. I cannot remember why I included it. Basically it is not possible for a child of a modal to be targetted via hash since this would hide the modal. So it might be ok to remove the check.

I will run some tests on this and check back soon!

Thanks for the PR.

@tzi, thanks for looking into this. I've now removed the check if the modal contains an ID since it is not necessary.
This closes the bug and we don't actually need the PR anymore :)

Less code for less bug.
It is the better way to fix issue :)
