How to reproduce:
1. Open the user's attached project ("case_1134615-AddressablesTest.zip")
2. Open the repro scene ("SampleScene")
3. Build Addressable Asset Bundles
4. Enter Play Mode
5. Inspect the text in the upper left corner of the window

Expected results: TMP text shaders render normally
Actual results: TMP text shaders do not render

Reproducible with: 2018.3.9f1, 2019.1.0b7, 2019.2.0a8
Could not test with 2017.4 as it doesn't have Package Manager and the Addressables package

Notes:
1. This project requires the Addressables package for reproduction
2. Doesn't reproduce on standalone
3. To reproduce the issue, assets must be built on WebGL platform
