ECL Watch WU Inputs grid spacing incorrect

The Dojo version of a tree grid can sometimes have too much space for expanded items.

An example issue on the 160 would be W20221024-123050. It appears that the renderQuery function of OnDemandList will calculate the height of the expanded section incorrectly. The count being used is always 19, which is the total number of inputs instead of the count of child items within each expandable item.
