Dropdown fills screen when it intersects with window side

[ghost]

Expected behavior

Dropdown doesn't fill screen when it intersects with the side of the window.

Actual behavior

Dropdown does fill entire screen when it intersects with the side of the window.

Steps to reproduce

Resize window so right side would intersect with dropdown. Hit dropdown button. Dropdown fills entire screen.

Plunker

You must resize the preview to replicate.

The size needed to replicate this in the plunkr is not plausible, but we are seeing this on the sort dropdown on a tile on the right side. When the window is small enough such that the dropdown touches the right side of the screen, the behavior happens.

Yeah the solution for this will just be to do smarter positioning for dropdowns like how datepicker works. Filling the entire screen is how drpodowns are supposed to work if there's not enough room, but in that case, it should just open to the left instead.
