Regarding WebGL build issue, it cannot be resolved because WebAssembly does not enable fine-grained control of numerical accuracy in physics simulations, so simulation consistency (compared to other platforms) will unfortunately not be possible to guarantee. If you want to get a more detailed explanation, please visit https://github.com/WebAssembly/design/issues/1429. Thank you!

How to reproduce:
1. Open the user-attached “FloorIsLava.zip“ project
2. Build the project
3. Run the Build and observe the falling objects
4. Build for a different Target Platform
5. Open the second Build on the other OS and observe the same objects

Expected result: In both of the Builds objects end up in the marked areas.
Actual result: Depending on the Build's Target Platform, the objects end up in different places.

Reproducible with: 2020.3.40f1, 2021.3.11f1, 2022.1.18f1, 2022.2.0b9, 2023.1.0a12

Reproducible on: macOS 11.6.5 (Intel), Windows 11

Note: The same differences in behavior can be seen in the Editors for different platforms when entering Play mode.
