Originally this change was intended as the solution to accidentally maximizing Chrome by double-clicking on the new tab button. This solution does work but another one is being coded for a more general problem. This change solves also the accidental maximizing of Chrome when double-clicking the close tab button except on the last tab (rightmost in LTR systems). See issue 2827 for further details.This change removes a band-aid which did not perform a hit-test on the tab-strip while it is animating in order to avoid unknown chromebot crashes as reported by Ben. The removal of the fix makes the hit-test perform as expected.Trying this now, at Peter's suggestion, so that we can measure and diagnose potential problems hidden by the said band-aid.
