safari: 4.0.1 Widgets no longer drag

[wurambo]

Subject of the issue

On Safari, the widgets are no longer draggable within their own grid. I am able to reproduce this issue with a few demos - https://gridstackjs.com/demo/two.html https://gridstackjs.com/demo/web2.html

edit - I had assumed it was only when multiple grids were rendered, but there are demos where there is a single grid and drag and drop stop working

Your environment

Safari Mac Version 14.0.3 (15610.4.3.1.7, 15610)
Gridstack v4.0.1

Steps to reproduce

Attempt to drag a widget to another spot in the grid

Expected behavior

Should let you drag to another spot in the grid

Actual behavior

Does not allow user to drag the item to another spot

so even the simple https://gridstackjs.com/demo/float.html doesn't let you drag (see placeholder) correctly ?
(nothing to do with multiple grids if that the case)

Looks like that demo is fine. The only two I'm running into so far is these two demos

https://gridstackjs.com/demo/two.html https://gridstackjs.com/demo/web2.html

Not exactly sure what these two have in common though - maybe having more than one droppable area?

so https://gridstackjs.com/demo/float.html you can see the dash-line placeholder when moving the item around just fine and it moves there ?
but doing exactly the same within the FIRST grid in https://gridstackjs.com/demo/two.html does not ? (don't try to drag between or from the new items yet)

does https://gridstackjs.com/ first example (same as web1.html BUT with jquery instead) work correctly ?

I don't have easy access to safari for testing. thanks.

For (https://gridstackjs.com/demo/float.html), everything is working as is. You can see the dash-lines and you and move the item around

https://gridstackjs.com/demo/two.html Does not show lines or let you move the item to another spot

https://gridstackjs.com/ both examples are working

Still not entirely sure what could be the culprit of these safari issues
