UI Rendered Twice.

Had this issue with the Typescript game, Warship (https://github.com/Microsoft/TypeScriptSamples/tree/master/warship). Without Heatfiler profiling, it gives only 2 dark-blue squares, the left one for human and right one for computer. With Heatfiler, it gives 4. Attached is a screenshot. As I cannot attach the warship.js file, it can be generated from the READ-ME instruction in the link above.
