When scrolling the content of a div with "overflow-y: scroll" the div will be drawn in the wrong layer or disappear completely if the page contains a Flash object and multiple layers. This issue only reproduces on Mac OS X 10.6 with Flash 10.1. Based on nightly builds the regression window appears to be r58875-r59046.
