This was caused by the `mb_data->obmat[]` being wrong because they are now shared between the particle system and the object. But Hair need the dupli parent matrix instead of the object matrix. Disabling `Show Emitter` option fixes the bug. To avoid this problem, request a different `EEVEE_ObjectMotionData` for particle systems using a different key pointer in the hash. This is a bit dirty but there is less code polution using this workaround. Differential Revision: https://developer.blender.org/D14911
