Dropdown not centering on screen despite dimensions

[Shringe]

Issue description

I want to set a "maximized" dropdown. Whenever I set the dimensions accordingly, the dropdown is a couple pixels to the bottom right of where it should be, leaving a small gap in the upper left, and hanging slightly off the screen on the bottom right. The bottom and right borders being off-screen is the easiest way to see this effect.

This seems to happen to all dropdowns actually, but it is most noticeable here.

I wonder if this is to do with the border widths. I'll take a look later.

Found the problem. Will work on a fix when I can.
