Ubisoft used to use ScaleForm, the alternative Flash runtime for games, for a lot of the Assassin's Creed games. I know some games use a specialised version of WebKit, for example Sea of Thieves uses Coherent UI[1]. There's also Ultralight[2] (ex Awesomium) which is similar. Games using vanilla Unreal Engine can use what they call UMG, but otherwise there's plugins for most frameworks. Some other games have completely custom frameworks of course.
