Introduce Using removes empty line whitespace in code

When using "Introduce Using Statement" the whitespace (empty lines) in the code block are removed. (See attached screenshots)
Steps to Reproduce:
Select a code block with white space between lines of code and use "Introduce Using Statement" and the code will contract as the white space between lines of code is also removed.
For example:
        [TestCase]
        public static void IndexRedirectsToLandingPage()
        {
            // Arrange
            AdminController controller = new AdminController();
            // Act
            ActionResult result = controller.Index();
            // Assert
            Assert.NotNull(result, "Expected non-null result");
            RedirectToRouteResult routeResult = result as RedirectToRouteResult;
            Assert.NotNull(routeResult, "Expected the result ot be a RedirectToRouteResult");
            string controllerName = routeResult.RouteValues["Controller"] as string;
            string action = routeResult.RouteValues["Action"] as string;
            Assert.AreEqual("Admin", controllerName, "Expected the controller to be 'Admin'");
            Assert.AreEqual("Home", action, "Expected the 'Home' action");

}
Actual Results:
[TestCase]
        public static void IndexRedirectsToLandingPage()
        {
            // Arrange
            using (AdminController controller = new AdminController())
            {
                // Act
                ActionResult result = controller.Index();
                // Assert
                Assert.NotNull(result, "Expected non-null result");
                RedirectToRouteResult routeResult = result as RedirectToRouteResult;
                Assert.NotNull(routeResult, "Expected the result ot be a RedirectToRouteResult");
                string controllerName = routeResult.RouteValues["Controller"] as string;
                string action = routeResult.RouteValues["Action"] as string;
                Assert.AreEqual("Admin", controllerName, "Expected the controller to be 'Admin'");
                Assert.AreEqual("Home", action, "Expected the 'Home' action");
            }

}
Expected Results:
[TestCase]
        public static void IndexRedirectsToLandingPage()
        {
            // Arrange
            using (AdminController controller = new AdminController())
            {
                // Act
                ActionResult result = controller.Index();
                // Assert
                Assert.NotNull(result, "Expected non-null result");
                RedirectToRouteResult routeResult = result as RedirectToRouteResult;
                Assert.NotNull(routeResult, "Expected the result ot be a RedirectToRouteResult");
                string controllerName = routeResult.RouteValues["Controller"] as string;
                string action = routeResult.RouteValues["Action"] as string;
                Assert.AreEqual("Admin", controllerName, "Expected the controller to be 'Admin'");
                Assert.AreEqual("Home", action, "Expected the 'Home' action");
            }
