Is that a problem?

  If you consider UI elements moving around dynamically to be a problem, which I'm guessing these guidelines do. Also if you consider scrolling like an epileptic having a fit to be a problem.

    I don't believe that's the case. Sticky elements aren't uncommonly used in iOS at least. If there's guidance about interface elements not behaving the way you're describing, I didn't see it in glancing through the guidelines. For what it's worth I don't see any "scrolling like an epileptic having a fit" behavior in Safari. It's difficult to understand your criticism when you aren't expressing it in meaningful terms, however.

      Excuse the bad ASCII, but the page is laid out like this: ------- |--1--| ------- |--2--| ------- |3|-4-| ------- |--5--| 1. Will scroll normally and disappear from the view port. 2. Will scroll a little bit, then become sticky 3. Will over scroll a little bit at the start (the gap between "human interface guidelines" and "overview" is bigger at the very top), then become sticky until you get near the bottom and will then become sticky again. 4 and 5. Will scroll normally. This goes beyond sticky elements, it's sometimes sticky, sometimes moving elements, It's unexpected and confusing behavior. Not confusing enough that anyone will get lost, but confusing enough that your eye's get drawn to other parts of the page because they start/stop moving as expected at various times.

        3 is the only "weird" part. Sticky elements are nothing new. And a TOC sidebar being somewhat sticky isn't really all that weird anyway.

        I think we'll have to agree to disagree on this one. Sticky elements are a somewhat new mechanic on the web, and if used inappropriately I agree they can cause confusion, but I don't see that in this particular instance. Certainly nothing that resembles an epileptic seizure.
