[WebGL] Build stalls on load and periodically freezes for multiple seconds when GPU Instancing is enabled on a Material
How to reproduce:
1. Open the user's project
2. Build project with scene "MainScene" for WebGL
3. Run program in a browser and observe stalls
Expected result: the scene is shown immediately after the "Made with Unity" screen. The 3D grid of cubes spins smoothly in view at all times
Actual result: the "Made with Unity" screen is followed by a long stall (~10 seconds) before the scene is shown. The 3D grid of cubes periodically freezes while spinning
Reproducible with: 2017.4.19f1, 2018.3.4f1, 2019.1.0b2, 2019.2.0a3 (only on Google Chrome and Mozilla Firefox)
Note: the issue does not reproduce on Microsoft Edge. Also, the periodic freezing at runtime stops after ~5-10 seconds in the repro project
