This does not look like it should be oauth2.el work to add workaround on
this.

Since it's likely that the Web page is a real web Page, what about
providing an Emacs function like `browse-url-with-a-capable-browser'
which would act like `browse-url' but will be defaulting to a capable
browser and will indicate to the user that it should not set this to
something that is not?
