I think this is an exploit.

not in creative but survival mode only

In singleplayer I'm able to use the visit button to teleport around my world, even tho, i not playing in creative.

multiplayer not in creative, not opped, survival only

ok, very good, on a server it behaves.

Notes:

i think it shouldn't allow it single player unless the player is explicitly in creative mode.

I'd be concerned if this was exploitable in multiplayer, but players already have a plethora of ways to cheat in singleplayer. I'm open to pull requests to add this feature, though.
