this is no longer testing constructing an element from an html snippet like in
testConstructorHelper in element_test.dart. Is this intentional?

[blois, 2012/12/28 00:43:27]

Yeah, basically the old way tested the HTML parse rules for elements, which are
considerably more complex than creating tags. This is great if we're generating
HTML and want to validate that it works across browsers, but for our uses it
introduces a lot more variability than necessary.

Some elements allow content, some do not, some defaulted to having content while
others did not, etc.
