If the itemssource for a combobox is set to a large number of items sometimes when you expand the dropdown it has no border. Then if you collapse it and re-expand it the border will appear.
Attached are two images of the same dropdown, one with the border and one without.
You can continually open and close the dropdown to see that sometimes the border is there and sometimes it is not.
Thanks in advance for your help!
