Expected behavior

The WASM target framework should build correctly

How to reproduce it (as minimally and precisely as possible)

Create a new Platform Library project using the 5.2 templates
Include all frameworks
<TargetFrameworks>net8.0;net8.0-ios;net8.0-maccatalyst;net8.0-android;net8.0-windows10.0.19041;net8.0-browserwasm;net8.0-desktop</TargetFrameworks>

In the project file change
<ImplicitUsings>enable</ImplicitUsings>
To
<ImplicitUsings>disable</ImplicitUsings>

@BrianDT A possible workaround is <UnoDisableFilterWebSdkGlobalUsings>true</UnoDisableFilterWebSdkGlobalUsings>.
