{{EventRef}} macro has started throwing errors

[chrisdavidmills]

For example see:

• https://developer.mozilla.org/en-US/docs/Web/Events/responseprogress
• https://developer.mozilla.org/en-US/docs/Web/Events/requestprogress
• https://developer.mozilla.org/en-US/docs/Web/Events

The error is

    1 | <div>{{EventRef}}{{SeeCompatTable}}</div>
-------------^
    2 | 
    3 | <div>

TypeError: ejs:1
 >> 1| <%
