ParticleSystem Birth SubEmitter doesn't always fire when using random between two constants lifetime

Shuriken

-

Steps to reproduce:
1.Open attached 'SubEmitterLifetime' Unity project
2.Open scene ‘MainScene’
3.Enter Play mode

Expected results:
Birth and Death Sub Emitters have an equal amount of particles
Actual results:
Birth Sub Emitter has fewer particles

Reproduced in: 2017.3.0a4, 2017.2.0b7, 2017.1.0p3, 2017.1.0f3, 5.6.3f1, 5.5.4p2

Note: Random seed affects the number of missing particles. It also seems that certain Start Lifetime ranges have more particles missing than others, for example, 0.100 to 0.135 has no missing particles, 0.135 to 0.140 has quite a few missing.
