In the Monument Tower you can see Elizabeth opening her first tear which shows Paris in the 80s. In the background there’s a movie theatre where a film called “La Revanche du Jedi" is playing.
This is the French title of “Revenge of the Jedi" which was the original title of "Star Wars Episode VI: Return of the Jedi”. In December 1982, George Lucas decided that “Revenge" was not appropriate and changed the title to "Return”.
This reference also suggests that Elizabeth opened a tear to an alternative universe where the title never got changed.
