The :active selector is applied on elements with draggable=true but the setting for the cursor property is not. This occurs in Safari 6.0.2 (8536.26.17) and Chrome 24.0.1312.56 on Mac OS 10.8.2 To reproduce: 1. visit http://jsfiddle.net/itaylor/FXd8f/ 2. Drag the pink "Drag Me" element Expected: the box turns lightgreen while active and the cursor changes to -webkit-grabbing's grab hand. Actual: the box turns lightgreen while active and the cursor changes to the default pointer. The issue occurs with any value of cursor property, it is not limited to -webkit-grabbing. Firefox 18 does not exhibit this behavior, correctly taking -moz-grabbing (although it has some other bugs I'll be filing)
Safari, Chrome, and Firefox all agree on rendering for this test case. I don't believe there is any remaining compatibility issue.
