Fix tier list maker tab switch scrolling to the top

The key was added in e1da2741d ("Fix switching tabs making the item pool
unresponsive") as a workaround for an unknown root cause. The drag & drop
code has changed a lot since then, and dragging with mouse or touch in any
direction after switching tabs now works without the remount, so this
removes it.
