If you jump onto the ventilator installed on the floor, you should be able to float higher and higher in the air, but you can't. This issue only occurs with the ventilator in this section. After this scene there's no problem at all. This issue appears to be a regression caused by e894d4d.

Could this be another FIPR issue? If so, then fixing this could break other games such as the physics in Sonic Adventure.

No, it looks like an SH4 operations timing issue. But fixing it may break other games nonetheless.
