This makes a very noticeable/sizable flash/jump in the scrolling when you expand a tree node because the expansion instantly creates a whole screen height's gap between nodes before collapsing down to the children that actually exist. If this height is needed, maybe we could have it conditional on if there is no priorPreload?
