It doesn't need to be a modal and can (should!) fall back to a simple <a> without JS. It also didn't work even with JS for me.

First, you're assuming my entire website should work without JavaScript. You don't understand my design reasoning, nor have you asked about the underlying cause.

Second, for a modal, I should use a `<dialog>` that opens via a `<button>`, which it already does. JavaScript does the magic. Not a `<a>` as you suggested.

Finally, if it's a bug, which I find very strange because it's a very simple piece of code and no one has reported it, you're not posting it in the right place. An email or the contact form would have been more appropriate.
