Apparently the Scrolled method creates a frame into which the listbox and scrollbar widgets are placed. I'm guessing that the frame somehow gets in the way of changing the listbox dimensions.

choroba's observation that a plain listbox could be modified inspired me to investigate further, leading to the solution I mentioned above. So thanks, choroba!
