DevTools: fix changing of cursor while dragging

DevTools: fix changing of cursor while dragging

We used to change cursor upon drag on body only, but this now doesn't
have effect since we explicitly set cursor: default in .component-root.
So set the cursor explicitly both on the event target and body (the latter
is needed so that cursor change also has effect on the glass pane).

Shouldn't this be behind if (oldcursor) ?
