preLaunchTask not run on Blazor WebAssembly Hosted app

## Issue Description ##
Despite configuring a preLaunchTask to build (using `dotnet build`) on a Blazor WebAssembly Hosted app in the .vscode\launch.json and .vscode\tasks.json files, the task is not run. The task is run when the C# extension is disabled (however, this leads to the launch failing, as the `ms-dotnettools.blazorwasm-companion` also becomes disabled, leading to the error message "Configured debug type 'blazorwasm' is not supported.").

I searched for a similar issue, but I could not find one. My apologies in advance if there is such an issue and a solution. If that is the case, kindly provide the link.

## Steps to Reproduce ##
1. Create a new Blazor WebAssembly Hosted app by running 'dotnet new blazorwasm --hosted').
2. Use the following configuration files in the .vscode folder:

*launch.json*:
```json
{
"version": "0.2.0",
"configurations": [
{
"name": "Launch and Debug Standalone Blazor WebAssembly App",
"type": "blazorwasm",
"preLaunchTask": "build",
"request": "launch",
"cwd": "${workspaceFolder}/Server",
"hosted": true,
"program": "${workspaceFolder}/Server/bin/Debug/net7.0/TestBlazorWasmApp.Server.dll",
"url": "https://localhost:7220",
"browser": "chrome"
}
]
}
```

*tasks.json*:
```json
{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
{
"label": "build",
"command": "dotnet",
"type": "process",
"args": [
"build",
"${workspaceFolder}/TestBlazorWasmApp.sln"
],
"problemMatcher": "$msCompile"
},
]
}
```
3. Select the "Launch and Debug Standalone Blazor WebAssembly App" debug configuration.
4. Modify any source code file in order to cause deliberately a compiler error.
5. Save the file.
6. Debug (e.g. by pressing F5).

## Expected Behavior ##
The `dotnet build` command should be executed before launching the apps. The build would result in an error and the apps would not be launched.

## Actual Behavior ##
The apps launch immediately.
