Test Case

Steps to reproduce

Create a canvas inside a container. The container must have overflow. The canvas must be larger than the container.

You can scroll the canvas on desktop; you can't on touchscreen, even with allowTouchScrolling.

Expected Behavior

You can scroll the container on touchscreen.

Actual Behavior

You can't scroll the container on touchscreen.

I did some investigation. Fabric.js applies touch-action: none to the canvas style. Removing that allows scrolling.

An easy fix would be checking allowTouchScrolling, and if that is true, we don't set that style.

yeah this is an idea
