Thanks,

Do you have the issue on a desktop or on a touch device?

I can reconstruct the issue on the desktop
On touch devices, the same situation can appear if you try to scroll the combo, which already at the end of the list, in such case UI will locate the parent UI with scroll, and scroll it instead of the combo. ( this is the way how native HTML scrolls work on touch devices )

I have this issue on desktop
