fix: drag-and-drop — use fromHandle bool instead of e.target check

e.target in dragstart is always the draggable item element, never the
handle child — so closest('.pl-drag-handle') always returned null and
every drag was cancelled. Now mousedown on handle sets fromHandle=true
and item.draggable=true; dragstart checks the bool instead.
