Steps to Reproduce

Enable the setting "powershell.codeFormatting.whitespaceBetweenParameters":

workspace.json

{
	"folders": [
		{ "path": "T:/Test/PowerShell" },
		{ "path": "C:/Program Files/PowerShell/Modules" }
	],
	"settings": {
		"powershell.cwd": "PowerShell",
		"editor.wordWrap": "wordWrapColumn",
		"powershell.codeFormatting.autoCorrectAliases": true,
		"powershell.codeFormatting.avoidSemicolonsAsLineTerminators": true,
		"powershell.codeFormatting.pipelineIndentationStyle": "IncreaseIndentationForFirstPipeline",
		"powershell.codeFormatting.trimWhitespaceAroundPipe": true,
		"powershell.codeFormatting.useConstantStrings": true,
		"powershell.codeFormatting.useCorrectCasing": true,
		"powershell.codeFormatting.whitespaceBetweenParameters": true # ENABLE TO SEE IT
	}
}

Testie.ps1

Describe 'describe something' {
    Context 'do something in context' {
        It 'to the test' {
            # test something
        }
    }  -Tag test # double space before '-Tag'
}

Now press "SHIFT + ALT + F" and see the new broken code:

Describe 'describe something' {
    Co-Tag test # double space before '-Tag'
}

When the setting "powershell.codeFormatting.whitespaceBetweenParameters" is false, the issue isn't happening.
