[Tim Nguyen (:ntim)]

The <dialog> element should emit a "close" event.

You can forward declare EventSender with

template<typename T> class EventSender;

so you don't need this include in the header (slightly reducing header bloat and so improving compile times). See the other EventSenders.

Modern replacement for typedef is using:

using DialogEventSender = EventSender<HTMLDialogElement>;

I find it more readable.

This should be renamed to setOpen since it is now a setter rather than a toggle.
No need for parameter name, it is obvious from context.

In fact, can do this:

    template<typename> class EventSender;
