[Wasm][net10] Building with WasmBuildNative and threading enabled fails with assertion

[jeromelaban]

Description

Building a browser app with both WasmEnableThreads and WasmBuildNative fails to startup the runtime.

Reproduction Steps

• dotnet new wasmbrowser -o mybrowserapp
• update TargetFramework to net10.0
• Add <WasmEnableThreads>true</WasmEnableThreads> and <WasmBuildNative>true</WasmBuildNative> properties
• dotnet run

Expected behavior

The app runs properly and the timer updates.

Actual behavior

Regression?

Yes, from net8 at least.

Known Workarounds

Not using WasmBuildNative, which is not possible when using module linking.

use dotnet publish

Configuration

10.0.100-preview.3.25125.12

Note, the issue only happens with dotnet run, dotnet publish works properly.
