In both Firefox and Chromium, upon clicking an article in GettingStarted, the console reports an error:

mw.Api error: http Object { xhr={...}, textStatus="error", exception= "" }

This is I think GettingStarted's prepareToSendOnTour() making an api post to set the userjs-gettingstarted-showtour user option to 0.

action=options&format=json&change=userjs-gettingstarted-showtour%3D0&token=4bf9599f4830316d4bdc4fd49a597cea%2B%5C

The user preference seems to be set to 0 despite the API warning and there isn't an actual API return failure, so maybe it's not significant.  It could be related to the apparent double calls to prepareToSendOnTour (bug 45824), or just making the API request and then leaving the page with window.location = url;
