[WebGL] Uncaught abort(-1) error in browser when running a built project which uses libassimp library
How to reproduce:
1. Open the originally attached project 'New Unity Project.zip'

3. Run the built project
Expected results: Project runs in the browser
Actual results: Errors regarding unresolved symbols in the browser console while loading
Reproducible with: 2019.1.13f1, 2019.2.0f1, 2019.3.0a11

- Assets are created in the Package folders when creating assets via custom buttons in the Inspector window or other windows
- “Select” windows are named differently on Windows and macOS
- [Windows] No minimum “Select” window size
- Enabling “Editor Extension Authoring” in UI Builder doesn’t dirty the document and saving with shortcut doesn’t persist the state
- WebRequest.Create() function fails with "URI prefix is not recognized" errors when the project is built for Linux Standalone or Windows Dedicated Server
Resolution Note (2020.1.X):
The linking issue occurs because .bc files distributed in a "TriLib - Model Loader Package" have been compiled with a different version of Emscripten. Starting from Emscripten 1.38.10 type "size_t" changed from "unsigned int" to "unsigned long", which results in different mangled function names. The issue should be resolved by recompiling the package .bc files with the same version of Emscripten as used in the the target version of Unity.
