Fix display of menu bar icon in fullscreen apps

I've removed the code that constantly brings the app to front in order to fix the bug where the menu bar icon is being displayed while in full screen mode. I must say that (as an iOS developer) I have no idea why this code is in the app. I have tested it and it seems to work fine without it.

Any insights as to why this code would be in the codebase? Does it break anything?
