Steps to reproduce

$myVarName = 123
& {
    $myVarName = 456
    $myVarName           # breakpoint here
}

While debugging the script above and stopped at line 4 ($myVarName), evaluate debugger call using context: 'watch', expression: '$myVarName' returns the value from parent scope (123).

Simply changing the expression to $myVarName; returns the local value (456). This points us in the direction of this method as source of the bug. https://github.com/PowerShell/PowerShellEditorServices/blob/00238cdd8322241276b9691dd96f1f1b860bd1f9/src/PowerShellEditorServices/Services/DebugAdapter/Handlers/DebugEvaluateHandler.cs#L63-L64

The evaluate-call in my scenario is made through using new vscode.InlineValueEvaluatableExpression(range, expression) which VSCode executes here

Expected behavior

evaluate should return the local value (456). The local value is shown in Variable Explorer, PSIC and by inline using vscode.InlineValueVariableLookup while stopped at the same location.

Actual behavior

Returns 123.

After executing $script:myVarName or $global:myVarName in PSIC and using step over, evaluate returns the newest value (no scope-preference/-priority).

Changing $myVarName in PSIC + step over updates variable explorer + vscode.InlineValueVariableLookup result, but evaluate doesn't care - still showing the latest parent-scope value.
