Experimental: Multiple sortable lists example flickers on Safari

[jasongerbes]

The multiple sortable lists guide in the new documentation site includes an interactive demo of column/item sorting.

In Chrome, moving items/columns works smoothly. In Safari, the moved item/column flashes between the previous location and new location.

Update: This issue affects both the iOS and macOS versions of Safari.

@clauderic, your progress update post mentions an "experimental" label.

It appears that label hasn't been set up yet
