Hyphen before parameter gets stripped on paste

[rockerinthelocker]

First opened here: PowerShell/PowerShell#15268

Thanks, @iSazonov! Indeed, the bug seems to be introduced in PSReadline 2.1! Still not resolved in 2.2.0 beta2.

Steps to reproduce

Copy and paste the following line into a Powershell Core console.

Optimize-Volume -DriveLetter C -Analyze –Verbose

Expected behavior

The hyphen before the Verbose parameter should be preserved.

Optimize-Volume -DriveLetter C -Analyze –Verbose

Actual behavior

The hyphen before the Verbose parameter has been stripped.

Optimize-Volume -DriveLetter C -Analyze Verbose

Environment data

Note: The bug affects PSReadline 2.1.0-2.2.0 beta 2.

@rockerinthelocker Note that the pasting works fine with Ctrl+v in PSReadLine. It only doesn't work when you paste with right click.
