Partial workaround: https://github.com/campmdabt/UnrealEngine/commit/ab5043526d40bdb6100ec213ada6ea0cf6ca560b
Selected option does not scroll into view when opening a combo box for the first time. It will only scroll into view if the combo box is clicked more than once (a 2nd, 3rd, ect...)
Expected: The "Selected option" that is set would scroll into view when opening the combo box the first time
Result: The selected option does not scroll in the view when clicking the combo box the first time (it will scroll into view after clicking a 2nd+ time(s)).
