Add explicit $timeout delay for determining drop direction
Add explicit $timeout delay for determining drop direction

In #setDropMenuLocation, the bounding rectangle for the menu was being
calculated before it was rendered causing the height to be 0.

For some reason the $timeout was not waiting for the digest cycle to
complete, however, adding a 100 ms delay consistently drops the menu in
the proper direction.

Fixes #399
