Ensemble source code styles not applied

- Run the ensemble app.
- Open any sample like Interpolator etc.
1) Click on the source code tab. You can see that the source code is colored. See CodeColored.png attached.
2) When you select all source code using Double click and then single click. The CSS styles are not applied immediately and hence looks black and white. See BlackAndWhite.png attached.
 If you click some where else (outside source code area) then styles are applied and the source code is colored properly.
