Yes, List with one cell height.
In continuation to my previous comment, looks like 8 of the first 23 calls when window is displayed for the first time
are NOT for the one visible cell. These 8 calls are for some intermediate cell. I added a single counter for all three
`computeXXHeight` methods and verified with a list of height of one cell. When `fixedCellSize` is not set, total
combined number of calls for a cell are, 1:-  15, when Stage is displayed for the first time.(+8 for an intermediate
cell, not sure why) 2:-  5, when the list item is selected.
3:-  5, when the Window is resized.
