Testcase in comment 1 works for me; nothing is added to the input as I try to type in it, as expected.

OK. I can't reproduce on win7 either with my normal browsing profile, but I _can_ reproduce if I turn off the html5 parser (so go back to the default setting). The problem is that <input> doesn't force a <body> in the old parser and the <script> ends up in <head> as a result, so runs before the <input> has been parsed and added to the DOM. So the getElementById returns null (as your error console should be telling you).
