I have noticed in the past few days , that occasionally the game finder creates a new tab or even a whole different page, it seems to be a random thing.
I clicked on the British aisle map, expecting it to simply fade in as usually, I ended up with a new tab, which displayed the map.
I exited and tried again, and was presented the close up of the map in the usual manner, no new page or tab this time.
I have had this happen a few times now, does not seem to be any rhyme or reason to it, that I can figure out.
Good news is that it doesn't hurt me in any way.
A curious site burp, hope it isn't a bad omen of things to come.
