System Information
Operating system: Windows-10-10.0.17134 64 Bits
Graphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 430.86

Blender Version
Broken: version: 2.80 (sub 74), branch: master, commit date: 2019-07-11 13:50, hash: 06312c6d2d
Worked: (optional)

Short description of error
particle emitting from first frame location of emitter and also the first few particles appear to freeze in mid air.blend, baking the simulation to keyframes returns the same result, so not related to:

https://developer.blender.org/T58044

Exact steps for others to reproduce the error
particle emitting from first frame location of emitter and also the first few particles appear to freeze in mid air.blend

add a particle system (emitter) to a moving object and press play. Happens on both rigid body dynamic driven objects and also after baking the simulation to keyframes.

See file, the particles initially emitted float in mid air completely frozen, whilst more particles continue to emit from that same location. Particles also continue emitting from the moving emitter.

It is related as the evaluation of rigidbodies are still evaluated the same way regardless of if you are baking or not.

Actually, the issue here seem that you also have a very bad dependency cycle in the example file. So that is an additional reason why it is not working.
