Vertical Tabs on Full Screen

[PressJump]

  This is the first browser I use with this new vertical tab setup, but as seen to the left in the attached screenshot (youtube video in full screen mode), the vertical tabs module is shown even when the browser is in full screen, unlike the normal horizontal tabs view. This seems like an oversight, but maybe it's just because the feature is still in development? Either way I wanted to bring attention to it, as ideally I'd like at least the option to have it be hidden when a Pulse window is in full screen.
