1585072 - new HTMLAudioElement() at console prompt gives an error; Learn More link takes me to one of two wrong pages

Status: NEW

(DevTools :: Console, defect, P3)

While working to update media documentation, I opened up the console in Nightly (2019-09-26) and typed the following at the console prompt:

new HTMLAudioElement()

This returned the following error:

TypeError: Illegal constructor. [Learn more]
    <anonymous> debugger eval code:1

This is where it gets weird. Each time do this and then click the "Learn More" link, I am taken to a different page.

So far, I've seen:

• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Not_a_function
• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Non_configurable_array_element

The text of the error in console does not match the text seen on either of these pages. Something is weird there, and should probably be investigated.

(Yes, I know that HTMLAudioElement() is not a valid constructor -- this is just about the error message itself)
