It is indeed a limitation of TypeScript’s static analysis…
I’ve found more often than not the benefits of being able to know exactly which type of element I’m getting, which attribute it may contain and direct links to MDN worth the cost of a small `instanceof HTMLAnchorElement`

![Screenshot of TypeScript’s type information for HTMLAnchorElement.href:
Returns the hyperlink’s URL.
Can be set, to change the URL.
MDN Reference
Full code snippet:
for (const email of document.querySelectorAll('a[href*="mailto:"]')) {
if (!(email instanceof HTMLAnchorElement)) continue;
const button = document.createElement("button");
button.classList.add("copy");
button.innerText = "Copy";
/** @type {number | undefined} */
let timeout;
button.addEventListener("click", () => {
navigator.clipboard.writeText(email.href.replace("mailto:", ""));
button.innerText = "Copied";
clearTimeout(timeout);
timeout = setTimeout(() => button.innerText = "Copy", 3600);
});
email.insertAdjacentElement("afterend", button);
