Problem in rendering the dropdown when it renders in the up direction.

[DhruvPrakash]

When the dropdown renders upwards and you search for something in the second half of the list, the result just floats in the air. You can replicate this issue by opening the bootstrap.html example and repeating the form group which contains the default implementation a bunch of times. Tested in chrome 41 and firefox 35.
Please refer to the attached image.
