After upgrade to Ubuntu 18.04, when I enable the Natural Scrolling setting and scroll with two fingers horizontally it works as if I didn't enable it, i.e. the behavior is the same as with natural scrolling turned off. However, when scrolling vertically it works as expected.
Is this intentional or it's a bug? Is it possible to enable natural scrolling along both axes?
My touchpad is ELAN1000 I believe (ASUS K501UQ laptop).
