I realized that due to e10s mochitests disabled, we won't test the default actions of wheel events without APZ. I manually ran the test without non-e10s mochitests. Then, I confirmed that it's all green.
On the other hand, there is a known bug in the patch. The multiplier pref for X axis is applied to deltaY if the wheel event should be treated as horizontal scroll. So, WheelEvent.deltaY may see odd delta value with it especially when the multiplier X is negative (meaning scroll direction is reversed) but multiplier Y is positive. With more complicated code, I can fix it, but I don't know if it's enough worthwhile... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1228250 Title: [Shift + Mouse-Scroll-Wheel] Does NOT Scroll Horizontally To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1228250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
