[iOS] UI elements not added when loading scene from AssetBundles

Steps to reproduce:
1. Open attached project
2. Open scene Main
3. In Editor select NavSample > Command1 (this calls BuildPipeline.BuildAssetBundles method with BuildTarget.iOS)
4. Select NavSample > Command2 (moves created Asset Bundle to another folder)
5. Build for iOS

Expected result: Text from scene "e01003-f00001-01-01_00001" is visible on the screen.
Actual result: Text is not visible.

Reproduced with: 5.4.3p3, 5.5.1p2, 5.6.0b6. iPhone 6 iOS 9.0.2.

Note:
Text is visible on Mac Standalone builds.

The code that generates Asset bundle:
BuildPipeline.BuildAssetBundles (
Application.dataPath,
BuildAssetBundleOptions.DeterministicAssetBundle |
BuildAssetBundleOptions.ChunkBasedCompression,
BuildTarget.iOS );
