The issue was reproduced on IE11. Horizontal scroll axis appeared when I decreased scale. I tried to use suppressScrollX: true and useBothWheelAxes: false but it doesn't work.
How can I remove x axis on IE11 while scaling?
I found the solution that works for me. However, using of suppressScrollX: true and useBothWheelAxes: false doesn't work, I removed x axis via CSS:
::ng-deep .ps--active-x > .ps__rail-x {
display: none;
}
