The magical disappearing toolbar!

I've been noticing a really annoying bug for the past week or two, similar to the one I've had where the site suddenly scrolls itself to the top and starts flickering. This one is really odd because one minute the toolbar is there and the next it snaps to the top of the page. Once in a while it snaps back and I notice all of the comments move down to make room for it, but it's quite annoying.

This is what it looks like when it snaps to the top of the page, position: fixed; top: 0; The comment toolbar is initially there, but I'm guessing you guys do some weird ajax probably trying to load another ad, and the container integrity falls apart.

If I unset postion: fixed; the toolbar immediately snaps back in place. If this is the case, why use position fixed in the first place?

@suicidesn0wman: What OS/browser versions are you using?

@wemmick: Same as previous posts.

Happens on both machines. Win 10/Chrome and Mac/Chrome all up to date with latest stable build.

@suicidesn0wman: Odd indeed. We'll look into it. Does it happen across all articles? And are you doing anything in particular when the comment toolbar shifts to the top of the page (scrolling/typing)? Any ad-blockers enabled?

@wemmick: Yes to AdBlock(though that isn't an excuse), and it is always when I am typing.

I have noticed it happening when posting new comments, posting a reply to someone elses comment, and also while sending a private message to another user. So far it has not happened on the forum pages or create a new thread page. Since they're all re-using the same forums css/js I figured that last bit might be important.

@suicidesn0wman: Alright, thanks for the details!
