How to prevent diagonal dragging event?

[aahedi]

When drag diagonally it always switches tabs.
It should switch tabs only when drag horizontally left-right or right left.

Only allow vertical scrolling and horizontal sliding.

Is there a way to handle tab switching events by horizontal sliding only?

So in code, change this:

event.preventDefault();

to:

if (event.cancelable) event.preventDefault();
