Why does Chocolatey hang when using Powershell ISE without the `-y` switch?

Question

When using PowerShell ISE with Chocolatey to install applications, if I forget the -y switch, it hangs waiting on some sort of "confirmation" that's not popping up anywhere?

I have to Ctrl+Alt+Del to kill PowerShell ISE and Chocolatey and it leaves things in half-way state.

This is what it looks like below:

In addition to the comments to the OP above, regarding PowerShell ISE not supporting (most) interactive console applications...

It is worth remembering that the REPL window in PowerShell_ISE.exe is not just some sort of docked PowerShell.exe console. Most of the time the user experience is the same, but this hides a number of differences:

Both these executables are host applications that run a PowerShell runspace (engine). You can even write your own application that "hosts" PowerShell. It is the host application that determines the user experience.
