The CTRL-U is just the HTML part of the page. Not the CSS, images, or the other ...

Source HTML even, so whatever javascript changed is not there.

But for fun and laughs I saved js-generated source of a pretty big web page, opened it, and then pressed CTRL-U. It took 50 seconds to generate and render the source view. No wonder...

> document.getElementsByTagName('*').length

< 956632

(should be fun to go deeper and save this html, and then go ctrl+u on that)

edit: Tried it and it's been choking on the next "level" for the past 9 minutes. The tab is at over 1.5GB memory, I'm going to kill it.
