Draggable Doesn't Recover Animation - H5

[edancanning]

Subject of the issue

After dragging an element on the grid, it no longer animates when moved by another draggable.

Your environment

Gridstack: 5.0.0 w/ H5 DnD

Steps to reproduce

You can reproduce in Gridstack demo: https://gridstackjs.com/demo/two.html

1. Drag an element around (notice other elements animate correctly)
2. Drag a different element
3. Move the first element using the second
4. Notice first element does not animate

Expected behavior

I expect any element to recover its animation after dragging

Actual behavior

Elements stop animating after being dragged

Potential Reason

In dd-draggable -> _removeHelperStyle()

Looks like timeout is being executed after helper is removed. So I'm assuming this is why it doesn't recover the animation

   setTimeout(() => {
                if (this.helper) { <-- false
                    this.helper.style.transition = this.dragElementOriginStyle['transition']; // recover animation
                }
            }, 0);

good eye - looks like style="transition: none 0s ease 0s;" is left behind after the first drag causing it to not animate further...
