Steps to reproduce the problem:
If an object on a page is not in view - so it could be visible if the page or frame was scrolled, then the rect reported by IAccessible2::accLocation to 3rd party AT products is incorrect. The rectangle reported has the wrong height and width (depending on which way the frame scrolls) and is reported at the wrong location.

What is the expected behavior?
the width and height should be the size of the object.
The location should be off screen, at a position where it is still relative to the page based on the scrolling ammount. 

What went wrong?
component:UI>Accessibility>Compatibility

The rectangle reported seems to have been moved and clipped to a 1 pixel sized object at the edge of the frame. This contradicts the specification for IAccessible::accLocation().

This means that an AT aid no longer can tell if an object is off-screen because it's not reported with an off screen rectangle, also an AT aid can not calculate correct values for IAccessible2::scrollToPoint() because it doesn't know where the object is or it's size.

Did this work before? Yes 63 (not sure what minor version)

Chrome version: 64.0.3282.140  Channel: stable
OS Version: 10.0
Flash Version: Shockwave Flash 28.0 r0

This is a critical regression. We are going to have to recommend that customers use Firefox until this is fixed.
