No, no, that was just an example, don't worry! We test with JS off as a rule of thumb. (The new fullscreen comment reply quoting the original comment is an example: we actually did a lot of invisible work so that people without JS don't have to do a bunch of scrolling past the comment you're replying to.)

...can you give me a screenshot, please? That sounds like something's messed up but I can't guess what it might be.
