This was used internally by `jquery.fullscreen` but now that we have all the logic inside this file, we don't need to store this information two places with a copy in `this.$main.data()`. We can use this.isFullscreen directly as they are always the same. Change-Id: Ie15729a038bc9c1f6278c0b068c0706620d95e93
