When running webassembly on my macOS client, I noticed that all scroll/mouse wheel actions are inverted.

Example:

https://s3.eu-west-2.amazonaws.com/wasm-qt-examples/last/qtquickcontrols2/contactlist/contactlist.html

Normal webpage:

Wheel up - scrolls page UP
Wheel down - scrolls page DOWN
Touchpad up - scrolls page DOWN
Touchpad down - scrolls page UP

WebAssembly:

Wheel up - scrolls page DOWN
Wheel down - scrolls page UP
Touchpad up - scrolls page UP
Touchpad down - scrolls page DOWN

So totally inverted as normal.

As well, scrolling with the touchpad is quite unresponsive/slow/inconstant.

(Note that in my macOS the mouse settings "Scroll direction: Neutral" is checked (which inverters mouse wheel to common mode throughout macOS)
