I made a scoreboard objective called "jumped" with the criteria "minecraft.custom:minecraft.jump" and it doesn't increment when a levitation effect pulls me down before the full jump can be done.

Could you attach a video showing this behavior? How is levitation "pulling you down"?

Attached, levitation pulls me down as a negative level (please don't close issue just because of this, it is clearly shown that I am jumping and the fact that the counter doesn't increment is a real bug).

Can confirm. Jumping with a levitation effect prevents the counter from incrementing (sometimes). However, this may be intended as usually, levitation prevents you from jumping.
Ah, well anyway it's a duplicate of MC-86191
