It should have been at the base of the combobox, just as it is for without border...although I don think it's related to this fix but seems to be a bug nevertheless (in Date/Time macos settings, popupmenu for editable combobox is at the base)

Adding 1 to the height would go back to the previous implementation, but it actually causes the comboBox to look more misaligned by 1 extra pixel. I can re-add the +1 to return to the original method if preferred.

I see the popup issue on my end as well. But this seems to be unrelated to the fix as you mentioned. I can create a separate JBS issue for this if needed.
