Wasmtime running .net web application console prints incorrect port information

When I use the `wasmtime xxx.wasm` command to run the .NET web application and specify the program listening port through `--tcplisten localhost:8000`, the console always prints ：
```
info: Microsoft.Hosting.Lifetime
Now listening on: http://localhost:5000
```
But the real port of the web application is not 5000

The command I use is as follows：

```
wasmtime webapp.wasm --tcplisten localhost:8000
info: Microsoft.Hosting.Lifetime
Now listening on: http://localhost:5000
```
