I have noticed that when testing my games, if I use the window that the game is playing in to do a quick google search, and then press the play button again from the web editor, Quest calls up the tab it was using before, but no game starts.

Whatever website is loaded into the tab is what is displayed.

Just to clarify, the Quest engine will open a new tab, play the game just fine.
when the url in the game tab is changed, and the Play button is clicked again, quest will call up the tab by Id, but not load a new game, it will just display the content currently in that tab.
