Selected option does not scroll into view when opening a combo box for the first time

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...)

1. Open the editor
2. Create a new widget blueprint
3. Add a combo box to the designer tab
4. Add 9 default options
5. Name the options Test1 -Test9
6. Set the selected option to be "Test7"
7. Set the max list height to be 50
8. Save and compile
9. Open the level blueprint
10. Add the widget to the viewport on begin play
11. Play in Editor
12. Click the combo box
13. Notice that the default selection (Test7) does not scroll into view the first time the combo box is clicked

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)).
