Arrow HTML source is not current

[pranavparikh]

Currently, when Arrow takes a "screenshot" of a failure, the HTML that it
outputs comes from this code:

webdriver.getPageSource().then(function(src) {
fs.writeFileSync(testName + "-" + count + ".html", src);
callback();
});

However, this always represents the state of the DOM when the page first
loaded, not the current state (which would be more useful). I'm not certain
how to get at the exact full current DOM, but I did get this far:

webdriver.findElement(webdriver.By.tagName("html")).getAttribute("innerHTML").then(function
(src) {
fs.writeFileSync(testName + "-" + count + ".html", src);
callback()
});

This at least gets the innerHTML of the element, which should contain at
least the part of the page you care about.

Am I completely off-base here, or is this something worth looking into?
