[Locked Fullscreen] Fix the vox panel inconsistency with the fullscreen mode.
Upon entering the fullscreen/locked-fullscreen while the chromeVox panel is working, You can see an empty bar in the top of the screen. 1. The fullscreen rect y dimension starts after the height of the chromeVox panel, and as we don't want the chromeVox panel to be displayed, its height should be removed from the calculations. UPDATE: This issue got fixed by another colleague. So I added a unittest, and removed two workarounds were added to fix this issue in the locked-fullscreen mode. (one was to disable chromevox panel upon starting the lockedscreen mode, and the other was to hide the vox panel specifically for the locked fullscreen mode) When a window is set to fullscreen
