in any other open tab, auto-hide addressbar/toolbar properly goes into hiding as soon as i begin scrolling, portrait or landscape. ONLY IN AN ABOUT:CONFIG TAB, auto-hide addressbar/toolbar requires that i 1) scroll all the way to end of page and then 2) vigorously & multiply scroll down, through the stuck bar. any upward scroll & i have to start from scratch. portrait & landscape. this Android alpha cancer has metastacized to Android beta. danged annoying. please fix this bug & don't regress it back in.
