https://en.m.wikipedia.org/wiki/Special:History/Barack_Obama works, but https://en.wikipedia.org/wiki/Special:History/Barack_Obama fails:
This page is not available on desktop. Please click the mobile view link at the bottom of the page.
I hit this issue earlier today when trying to switch back to the desktop site by URL munging.
This is a pretty bad user experience. If the "Special:History" name(space) is going to be reserved by the MobileFrontend extension, it probably ought to match user expectations on desktop by either loading the page history or redirecting to ?action=history.
This is related to bug 11456.
