WebGL build fails to execute 'querySelector' if the canvas id starts with a '#' in Unity Play

Web Platform


How to reproduce:
1. Open the attached project from ""
2. Navigate to "Publish" -> "WebGL Project" -> "Build and Publish"
3. When the build succeeds in publishing it'll open in an internet browser, then open the browser's Console and start the game

Expected result: WebGL build succeeds in ignoring '#' in the canvas ID
Actual result: WebGL build doesn't run due to a '#' in the canvas ID

Reproducible with: 2021.2.1f1, 2022.1.0a13
Not reproducible with: 2019.4.32f1, 2020.3.22f1, 2021.1.28f1

1. It appears that the new WebGL loader doesn't check for '#'
