[Shuriken] Sub emitters is not visible in the scene when Inherit is set to Size

Visual Effects - Legacy

-

To reproduce:
1. Open attached project
2. Open Sample Scene and press play
3. Press play and notice how the left side particle scene does not have backfire
4. Press on This one is broken prefab and in the settings> sub emitter change Backfire Inherit to anything else than everything and size.
5. Notice the backfire working

Actual result: The sub emitters inherit set to size does not be visible in the scene.
Expected result: Everything should work and sub emitter should be visible

Reproduced with: 2018.3.14f1; 2018.4.5f1 2019.3.0a11
Can't check on 2017.4 due to missing prefabs

Note: gif attached

  1. Resolution Note:

    The "broken" effect spawns particles that start with 0 size (see size over lifetime curve).
    The sub-emitter module spawns on birth, and the sub-emitter contains a single emission event at time 0.
    So 0 size is passed to the sub-emitter, and its particles have 0 size.

    For the "working" effect, the Size over Lifetime module has a curve that starts at more than 0, which is why it works.
