Describe the bug

Setting popover={true} in your JSX will generate popover="true" in the HTML. This sort of works in most browsers, but it is invalid and can cause Chrome (with SSR-generated HTML at least) and other tools to complain.

Per https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/popover, the only valid values for popover are "" (same as "auto") , "manual", "auto", and "hint" (experimental) .

However, the TypeScript definitions for this attribute are boolean | "manual" | "auto" | undefined, and setting it to a boolean gives you values of "true" and "false" instead of "" or unsetting it.

Steps to Reproduce the Bug or Issue

Set popover={true}, popover={false}, or just popover as a JSX attribute.

Expected behavior

As a developer, I expect:

• popover={true} and popover to generate popover="" or just popover in the HTML.
• popover={false} to unset the attribute
• popover="" to validate with TypeScript.
