There's an episode of Sailor Moon where she and Naru (and later Naru and Umino) are dancing to 'Moonlight Desetsu' (i.e the theme song). It's even worse in the 90s english dub when they're singing the English theme song (though they only sings the part before they get to the part where Sailor Moon's actual name is said). Is either one an example of 'Leaning on the Fourth Wall' or is it another trope?
I tried asking this on the Discord and got no answer, so I'm asking here.
