Their names must have come from a very old version of the app, they both toggle the fullscreen mode and rotate the screen depending on circumstances. So `fullscreenButton` -> `fullscreenToggleButtonSecondaryMenu` because it is only visible in the secondary video menu on some configurations. and `screenRotationButton` -> `fullscreenToggleButton` because it is the main fullscreen button next to the video progress bar.
