[WebGL] UI Elements appear smaller on builds than in the Editor when the Canvas Scaler is set to Scale with Physical Size

WebGL

-

Reproduction steps:
1. Open the attached project ("case_1221561-CanvasScaler.zip")
2. Switch Build Target to WebGL
3. Enter the repro scene ("SampleScene")
4. Make a WebGL build and run it
5. Compare the button inside the build with the button in the Editor

Expected result: Buttons appear to be the same size
Actual result: Button inside the build is significantly smaller

Reproduces on: 2019.3.0a11, 2019.3.4f1, 2020.1.0a26, 2020.2.0a1
Not reproducible with, 2017.4.37f1, 2018.4.18f1. 2019.2.21f1, 2019.3.0a10

Tested on: Chrome (80.0.3987.122), Firefox (73.0.1), using 27 inch Mac (5120 x 2880), but it also reproduces on high-rez Windows monitors

Notes:
1. Other Canvas Scaler options works without issues
2. Also reproduced on Windows machine with monitor resolution 3840x2160

  1. Resolution Note (fix version 2020.2):

    WebGL will provide approximate information about used DPI, based on the assumption that CSS inch is close enough to a physical inch.
