…ility container is changed externally. NIViewAccessibilityElement overrides UIAccessibilityElement behavior by delaying computing its accessibility frame (which is in screen corrdinates). In that case, the accessibility frame is computed upon request based on the position at that moment of the actual visual component made accessible. This holds true until the accessibility container is changed externally. For example, when the accessibility element is in a table view hierarchy). In that case, the initial accessibility container is changed to a UITableViewCellAccessibilityElement and frameInContainer becomes invalid. This commit invalidates NIViewAccessibilityElement's special treatment and fallback to the regular behavior.
NIPagingScrollView.pageInset if non zero will inset the page from full screen, thus making neighboring pages visible. This is useful for showing that there is scrollable content and presents a 'film-strip' like appearance. Note in this case we take on the page snapping responsibilities as UIScrollView is fundamentally view bounds oriented and doens't support edges of other pages showing.
The accessibilityFrame in NIAttributedLabel could be stale after animations. This commit fixes this by always recomputing the absolute position of the accessibilityFrame.
