Code Formatting : Whitespacing one line hashtable

Hello
I am looking for a improvment on the current formatting tools by adding a whitespace after open bracket and before closing non empty curly brackets like :

#Actual
$emptyHash = @{ }               # an empty Hash
$myHash = @{foo = "bar"}

#Expected
$emptyHash = @{}                # an empty Hash
$myHash = @{ foo = "bar" } #whitespace after `{ `and before ` }`

Additional information:

• I use the PowerShell extension on VS Code to format automaticaly my code on save.

• My settings.json file:

{
    "editor.formatOnSave": true,
    "powershell.codeFormatting.preset": "Custom",
    "powershell.codeFormatting.alignPropertyValuePairs": true,
    "powershell.codeFormatting.ignoreOneLineBlock": false,
    "powershell.codeFormatting.newLineAfterCloseBrace": true,
    "powershell.codeFormatting.newLineAfterOpenBrace": true,
    "powershell.codeFormatting.openBraceOnSameLine": false,
    "powershell.codeFormatting.whitespaceAfterSeparator": true,
    "powershell.codeFormatting.whitespaceAroundOperator": true,
    "powershell.codeFormatting.whitespaceBeforeOpenBrace": true,
    "powershell.codeFormatting.whitespaceBeforeOpenParen": true,
    "powershell.scriptAnalysis.enable": true,
    "files.trimTrailingWhitespace": true,
}

Regards,

The issue does not name files or tests. Start by locating the PowerShell code-formatting handling for one-line hashtables and reproduce the examples in the issue with the listed custom settings. Done means non-empty curly-brace hashtables receive surrounding whitespace while empty hashtables remain unchanged, with coverage for both cases.
