Please describe the problem:
I have no idea whether I have posted this in the correct category, or if it has been reported before, so please move/delete appropriately.

There is a minor cosmetic bug when opening a drop-down list near the edge of the screen.

To put it simply if there are 5 items in the list and the drop-down menu has 5 rows, instead of displaying all the items in the list, the menu will leave the first (say) 2 rows blank and only display the first 3 items. You then have to scroll down to get to the last 2 items, but once you do, you (correctly) cannot go back, i.e. put blank rows in the menu again.

I'd be happy to post a screenshot if you just tell me how... :)

Steps to reproduce:
Just open a drop-down menu near the edge of the screen


Actual results:
Read above.

Expected results:
There should never be blank rows in a drop-down menu.

Does this happen every time?
Not sure.
