Asp.Net comments cause VS Code syntax highlighting to stop working

Question

My .ascx file contains C# and HTML. Everything in VSCode is highlighting the syntax correctly up until it reaches <%-- insert dynamically generated text here --%>. After that, everything is white like text. All HTML/other code doesn't highlight and IntelliSense stops working. How do you stop VSC from doing this?

The following extension can be installed to help add in support for WebForms' ASPX pages and older razor syntax.
