[WebGL] AsyncGPUReadback.RequestIntoNativeArray displays incorrect frame count in WebGL Player when using Chrome or Edge browsers
How to reproduce:
1. Open the “Frame_Count_Bug” project
2. Switch build to “WebGL” (File > Build Settings > “WebGL” > Switch Platform)
3. Build And Run (File > Build And Run)
4. Click on the Button labeled “Render”
5. Observe the label “Frame Count”
Expected result: frame count is around 2-4
Actual result: frame count is around 201-203
Reproduced with: 2021.3.25f1, 2022.2.19f1, 2023.1.0b16
Could not test with: 2020.3.48f1 (Functionality is broken → frame count is constantly displaying “0”), 2023.2.0a14 (Player does not fully load)

Latest issues
- Texture Map Viewer shows "Loading..." text instead of indicating users that Baked Texture Maps are missing
- "Analyze Import Process" button misaligned in Import Activity window
- Text in “Baked Shadowmask” mode is difficult to read in Baked Lightmap Viewer when Editor theme is set to Light
- Mesh wireframe is difficult to see in Baked Lightmap Viewer window when texture opacity is maximized
- Informational text does not wrap and does not fit when the Viewer Window is opened by default
Resolution Note:
This turned out to be a bigger issue than expected and not one that can be solved without other regressions, due to how async readback works with WebGL.
