Unable to run background processes

It seems that IE can't currently execute background processes. This means that some scripts are not possible, for example, I'm trying to write a doc that will create and deploy a functions + storage application. To do this it is I am using the Functions Core Tools as follows:

Install dependencies

```bash
sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-$(lsb_release -cs)-prod $(lsb_release -cs) main" > /etc/apt/sources.list.d/dotnetdev.list'
sudo apt update
```

```bash
sudo apt-get install -y azure-functions-core-tools-4
```

```bash
export FUNCTION_RUNTIME_VERSION="20"
curl -fsSL https://deb.nodesource.com/setup_$FUNCTION_RUNTIME_VERSION.x | sudo -E bash -
sudo apt install -y nodejs
sudo apt install -y npm
```

Create local functions project.

```bash
func init --javascript
npm install
```

This works when running manually, but the `npm install` requires return to be pressed to get control back. In IE it never returns control, the "busy" indicator just keeps spinning:

```bash
\[2024-06-07T23:43:03.538Z] Worker process started and initialized.
/[2024-06-07T23:43:08.535Z] Host lock lease acquired by instance ID '000000000000000000000000B8866BB3'.

```
