I traced the issue using the developer console, and found that the page mangling is happening on line 6 of markdownify.js, which is part of this chrome extension. Sure enough, removing or disabling the extension will cause the page to render properly again.
This seems to be caused by issue #10, but since that issue is so stale I figured it may be a good idea to open a new issue. markdown-preview is a very useful extension, but I sort of need to be able to read documentation.
A good work-around might be to check document.doctype when deciding whether or not to render as markdown. This pre-rendered markdown file has a doctype of <!DOCTYPE html>, while a few actual markdown files that I checked have doctype of null. I would assume that this should catch quite a few cases where the extension is trying to re-render markdown that's already been rendered, without preventing it from attempting to render legitimate unrendered markdown unless somebody's being stupid about their doctypes.
