I'm not sure that's a bug, I think move_lock_y only blocks translation on Y, not rotation.
There used to be an angular axis block too, but @reduz removed the property in c7e4527 without clear explanation (by mistake?).

i also get this issue

so the move lock doesn't work, some of my objects are floating off

it is not the rotation, it is the position, it should lock the y position (same problem with other move locks x and z)

as a workaround specific to my game, so far this seems to work:

if translation.y != 0.0: translation.y = 0.0
