I don't think Elemental counts as that queer character was blink and you miss it.
Strange World had decent-ish gay representation, although because the movie as a whole was rather bad/bland, it unfortunately didn't have the impact it should have.
To date, I think Nimona on Netflix is the best queer representation I've seen in a family film. I can't see Disney making an animated movie like that with such prominent gay characters and LGBT themes in the current climate. Maybe in about six years, if the pendulum swings back in a more progressive direction, the company will once again consider taking a stab at significant representation.
