PowerShell(ISE): ligatures not working with dashes

[Halkcyon]

The -> ->> etc ligatures (including multi-dashes together: ---) do not form into ligatures in the PowerShell CLI or the ISE. I have not found this to be the case with the rest of the ligatures.

Already tracked in #259.

I’m going to close this as a duplicate. Nothing I can do about it
