AssetBundles containing particles with mesh shape emitter instantiates in wrong direction

Asset Bundles


Steps to reproduce:

1) Download attached project '' and open in Unity
2) Build 'asdf' scene and close Unity
3) Download attached project '' and open and open in Unity
4) In the top-level toolbar, click on Test >> Rebuild existing AssetBundles (current platform)
5) Wait until Unity will finish to build AssetBundles
6) Close Unity
7) Go to CreateAssetBundle folder >> AssetBundlesStandalone folder >> drag and drop assets_deco_017dbfdc.unity3d assetBundle in to built project's directory
8) Launch .exe file and you will see that particles will go forward instead of upward

Expected result: Instantiated particles should go upward(check attached gif 'noRepro.gif')
Actual result: Instantiated particles goes forward(check attached gif 'repro.gif')

Not reproduced with:
5.5.3p1, 5.5.4f1

Reproduced with:
5.6.0b8, 5.6.1p3, 2017.1.0b8, 2017.2.0a2

Note: Build didn't worked with 5.6.0b1 - 5.6.0b7, so I wasn't able to find the exact version where regression started
Works as expected if DynamicBatching is enabled in PlayerSettings before building assetbundles(Step 4)

Tested with windows 10

Fixed in: 5.6.3p2, 2017.1.0p5, 2017.2.0b6, 2017.3.0a3
