Version

5.0.0

In What environments are you experiencing the problem?

Chrome

Node Version (if applicable)

None

Link To Reproduction

Sandbox templates are wrong. Next template fails to install, Vanilla template >= v6 actually uses fabric v3 and fails to install as well.

Steps To Reproduce

1. Create a basic Fabric canvas in an Angular app (or plain JS app)

const canvas = new fabric.Canvas('canvas');
fabric.Image.fromURL('path/to/image.jpg', (img) => {
canvas.add(img);
});
2. Open the app on a mobile browser (Safari on iOS or Chrome on Android).
3. Try to drag the image on the canvas using touch.

Expected Behavior

The image should move (drag) smoothly on touch events, as it did in Fabric 4.7.x.

Actual Behavior

The image does not respond to touch/drag events on mobile devices.
No console errors appear, and the canvas otherwise renders correctly.
