Description

The PPR Blocking functionality works by blocking all mouse clicks between the start of a PPR update and the end. The element to return focus to, which is the activeElement, is saved off and then after the PPR update completes, focus is returned to it. The problem occurs when that element is PPR'd with another element. IE8 will throw and error and complain that the element is not focusable. While that error is not visible in the UI, it prevents further operations on the page. IE9 does not complain so this issue does not happen in that browser.
