Breaks on funny/broken HTML

[Prinzhorn]

I assume this is expected behavior, but I was kind of expecting morphdom to handle everything I throw at it.

This happened during live editing of markdown that is rendered using morphdom. The minimal repro is this :

const wrapper = document.createElement('div');

morphdom(wrapper, `<div><hr /></div>`);
morphdom(wrapper, `<div><hr /</div>`);

In reality I was literally just pressing backspace and removed the >. The above will throw

morphdom-umd.js:43 Uncaught DOMException: Failed to execute 'setAttribute' on 'Element': '<' is not a valid attribute name.

I'm aware that this HTML is broken, I just wasn't expecting morphdom to throw for some reason. The browser will happily turn this into "something", as it can't just crash obviously.
