Issue Description

PSReadLine Keyboard Commands do not work in the PowerShell Integrated Console

Expected Behaviour

Using keyboard combinations which are bound are executed.

Actual Behaviour

Attempting to use any keyboard commands does not work.

e.g. pressing Ctrl+l does nothing, even though it's bound by default to the below action

Ctrl+l        ClearScreen       Clear the screen and redraw the current line at the top of the screen

Attached Logs

N\A

Additional Notes

ms-vscode.powershell@2019.5.0 is disabled, I'm using ms-vscode.powershell-preview@2019.5.0

Reproduziere das Problem in der PowerShell Integrated Console unter macOS mit der Preview-Erweiterung und überprüfe, ob gebundene PSReadLine-Befehle wie Ctrl+l ignoriert werden. Als erledigt gilt die Aufgabe, wenn Tastaturbefehle wie erwartet in der integrierten Konsole ausgeführt werden; der Payload nennt keine Quelldateien oder Tests, die überprüft werden sollen.
