Blazor WebAssembly app fails with emscripten compiler options #37690
Description
Describe the bug
Blazor with WebAssembly does not work when attempting to debug applications using emcc compiler options such as ASSERTIONS, STACK_OVERFLOW_CHECK, and SAFE_HEAP.
To Reproduce
https://github.com/djsell/BlazorWasm
$> dotnet publish -c release
$> cd bin/release/net6.0/publish/wwwroot
$> dotnet-serve
Then load in the browser and check console log.
This project is just the Blazor template project + EmccCompileOptimizationFlag property added to the project file.
Exceptions (if any)
