False report of RCS1163

[wmjordan]

Product and Version Used:
Last released

Steps to Reproduce:
The following code triggers this issue on parameter DependencyPropertyChangedEventArgs e.

public static TextBox SetOnVisibleSelectAll(this TextBox textBox) {
	textBox.IsVisibleChanged -= TextBox_VisibleSelectAll;
	textBox.IsVisibleChanged += TextBox_VisibleSelectAll;
	return textBox;

	void TextBox_VisibleSelectAll(object sender, DependencyPropertyChangedEventArgs e) {
		var b = sender as TextBox;
		if (b.IsVisible) {
			b.Focus();
			b.SelectAll();
		}
	}
}

Expected Behavior:
The parameter e is necessary since the containing method is used in an event handler.
