The background here is that FullScreen is going away because Chrome now always allows FullScreen. We didn't want to remove this category altogether because there could be sites in the list below the toggle, and we need to surface that list to the user for privacy reasons. We also wanted to make minimal changes to the category code because it would all be throw-away work. Therefore we (UX and Eng) agreed to just disable the toggle and change the toggle text.

The suggestion to not make the category clickable if there's nothing in the list is fine... for FullScreen. But this category should just go away. I'll ask around for the status of removing the recorded permissions for FullScreen, which is blocking the removal.

Adding Matt, who did the work to disable the toggle for this category.

Matt, has the associated FullScreen data been deleted? And if so, can this category now be deleted? I'd be happy to review such change, if you want.

right, but also note: the toggle's button is transparent and looks like a rendering bug

As I recall, this is just the standard UI toggle in disabled mode. There's no styling involved so any rendering issues would need someone who knows about the default controls because I don't think we would special-case this to be all different.

emilyschecther@ to check with the eng who worked on this (I think there's plans for the design but can't remember the specifics!)

Sorry I missed this bug earlier.

This was by design, to show people that the fullscreen permission is always enabled now (while their content settings data is being stored). Though in hindsight we could've just got rid of this global setting sooner.

Oh well. I deleted it yesterday in r429474.
