Mouse position does not match in-game mouse position in WebGL builds when zoom attribute is added to div "unityContainer" block

WebGL

Jun 10, 2019

How to reproduce:
1. Open the attached project ("case_1161544-SimpleDemoProject.zip")
2. Open the repro scene ("SampleScene")
3. Build and run the WebGL build
4. Move the mouse around the scene
5. Confirm that the ray is following the mouse (in-game mouse position matches actual mouse position)
6. Apply "zoom" attribute to "unityContainer" div block
7. Move the mouse around the scene again

Expected results: The in-game mouse position matches actual mouse position
Actual results: The in-game mouse position does not match the actual mouse position

Reproducible with: 2017.4.29f1, 2018.4.2f1, 2019.1.7f1, 2019.2.0b6, 2019.3.0a6

Notes:
1. Tested with Google Chrome (Version 75.0.3770.80 (Official Build) (64-bit)) and Microsoft Edge (Microsoft Edge 42.17134.1.0) browsers
2. Setting the zoom back to the default value (100%) fixes the issue
