Keyboard/Select menu auto closes on Samsung Galaxy S3 if the input would be hidden by the keyboard

We have a select input quite far down the page, on the Samsung Galaxy S3 it uses a custom Samsung keyboard that brings up a keyboard like dialog for select inputs, when the input would be covered by this keyboard the keyboard is automatically hidden.

I've confirmed this by adding a large amount of padding below the element so I can scroll it past the keyboard area, and it shows fine and does not automatically hide the keyboard.
