Created attachment 438614 [details] testcase Besides overflow: hidden, overflow:scroll, overflow:auto and overflow: visible, there is also the computed value of overflow:-moz-hidden-unscrollable. The new autoscroll code should probably also take that into account, because now autoscrolling doesn't work with those values.
Created attachment 438699 [details] [diff] [review] fix [pushed: comment 4] Instead of disallowing scrolling on "hidden" or "visible", I changed it around to allow scrolling only when "scroll" or "auto" is present. Are there any other special values I need to be aware of?
See https://developer.mozilla.org/en/CSS/overflow It turns out there are also these values: -moz-scrollbars-none, -moz-scrollbars-horizontal and -moz-scrollbars-vertical. But for those values, the computed values are 'converted' into 'hidden' and 'scroll', so they already work correctly.
