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.
