Thank you for reporting a bug to Unity. After reviewing the behavior, we've confirmed it aligns with the current design and intended use of the feature. We understand this may differ from your expectations or workflow. We will close this case as 'As Designed.' If you have feedback on how the feature could better meet your needs, please let us know - we value your input and consider it in future improvements.

How to reproduce:
1. Create a new Unity project
2. In the Build Settings, switch to the "Web" Platform
3. Go to Edit -> Project Settings -> Player -> Web settings -> Publishing Settings -> WebAssembly Language Features
4. Set the "Initial Memory Size" field to 1 and observe the results

Expected results: The warning is thrown or shown in the box that the configuration is not appropriate
Actual results: No validation messages are shown and build fails with the "emcc: warning: -pthread + ALLOW_MEMORY_GROWTH may run non-wasm code slowly" error

Reproducible with: 6000.0.68f1, 6000.3.9f1, 6000.4.0b9, 6000.5.0a7

Reproducible on: macOS Tahoe 26 (M1)
Not reproducible on: No other environment tested
