Steps to reproduce the problem:
1. Do one of these:
1.1. Go to a page with unscrollable height, but with scrollable container which contains form with autocomplete=on. 
Example here: http://codepen.io/anon/pen/BzzrJg
1.2. Create a simple page with a form that has autocomplete=on. Set body overflow=hidden and some fixed height, set form container overflow=scroll, set form height bigger than body height.

2. Write something into input to bring on autocomplete box.

3. Scroll form container down with a mousewheel/touchpad/

What is the expected behavior?
Autocomplete box disappears or scrolls together with  it's corresponding input.

What went wrong?
Autocomplete box detaches from it's corresponding input and stays afloat, absolutely positioned against window. Just like in this old issue: https://bugs.chromium.org/p/chromium/issues/detail?id=25232
(seems like it has been fixed for scrollable body only).

Did this work before? No
