Originally implemented to handle resizable ComboBox windows, this "feature" no longer exists, so calculating min size is no longer necessary. The calculation was also failing to account for dynamic ListViews properly. This patch simplifies things by setting ComboBox ListView's minimum size explicitly and deferring to AbstractScrollableWidget's more flexible calculated implementation otherwise. Fixes FontPicker resizing incorrectly due to overly rigid ListViews.
