Overflow adjust not working properly when parent has overflowY

[bryceosterhaus]

I found this issue while working with some fixed elements that have overflow styles in the parent. Is this expected? I would think that the adjust feature would pull the element back into the viewport.

Expected Result: Clicking on button would auto adjust dropdown to be within the window.

Actual Result: Dropdown element flows off of page, adding a scroll in the x direction.
