Confirm if Screen.fullScreen works for webGL in a browser?

From what I can tell (through fruitless attempts and tests) Screen.fullScreen does NOT get set to true when the browser makes the content go into full screen mode. (Unity 5.6.2)

Can anyone else confirm this?

If it is true and official, the documentation needs to say that it is not supported in webGL!
https://docs.unity3d.com/ScriptReference/Screen-fullScreen.html

If it is a bug, then let me know so I can report it.

 

Can I delete this thread? The lesson I learned is I need glasses!
