Description

When finding .wasm files in detect_features_and_polyfill, the scriptUrlQuery variable is derived from the importing module (import.meta.url) instead of where the blazor.boot.json file is, and there does not appear to be any way to configure it to look in a different path.

This means that bundlers which generate a module which imports the dotnet runtime will struggle to put the generated module into a _framework folder alongside the rest of the .NET/wasm assets.

Reproduction Steps

Create a vite project, import a .NET wasm assembly based project, build the vite project.

Expected behavior

The default behavior for loading .wasm files should be that it loads from the same directory as the blazor.boot.json file, or else provide a configuration (ala ".withConfigSource()") which allows the caller to specify where the .wasm files are stored.

Actual behavior

the bundled javascript attempts to load the .wasm from whatever path it's currently on.

loader/polyfills.ts:42

without any possibility to configure where the assemblies actually are; i.e. "./" instead of "./_framework/*"
