Continues scrolling on mobile

[weaselpus]

Environment

• Browser: Safari, Chrome on mobile
• Version of smooth-scrollbar: 8.5.2

Issue Summary

Continues scrolling on mobile is stuck easily.

Current Behavior

When a user scrolls vertically and reaches the edge, the continues scrolling doesn't kick in when the user scrolls a tiny bit the x-axis too.
Which happens usually when user scrolls up and down with their thumb on mobile.

Expected Behavior

The scrollbar continues scrolling along the y-axis even when users don't scroll perfectly vertical on touch devices.

Steps to Reproduce

On mobile go to the demo page.
Disable "Overscroll-plugin" and enable "continues scrolling"
Test "continues scrolling" on the last picture.

Fix

Remove "x-axis checking" in scrollbar.ts by removing line

smooth-scrollbar/src/scrollbar.ts

Line 457 in 014416e

res = res && (destX === offset.x);

and

smooth-scrollbar/src/scrollbar.ts

Line 451 in 014416e

const destX = clamp(deltaX + offset.x, 0, limit.x);
