Remember previous height of Dropdown Menu edit window

Often when working with the Dropdown Control effect, I'll have more options than can be shown in the default height of the Dropdown Menu edit window. I can of course resize that window to be taller, to show more options. However, if I were to close and later re-open this (or any other) edit window, it reverts to the default height, meaning that I have to repeatedly resize it to be able to work efficiently.

It would be helpful if the previously set height of this window is remembered, and used when next opened.
