hx-boosted forms issue requests even when method="dialog" or formmethod="dialog"

[PizzasBear]

As I understand it, hx-boost is meant only to replace standard browser requests with htmx ajax ones.
When using method="dialog" or formmethod="dialog" the browser doesn't issue a request, so hx-boost shouldn't to intervene.

Example:

<dialog open>
    <form hx-boost="true" method="POST" action="create">
        <h1>Create a new thing</h1>
        <p>
            <label>
                Name:
                <input type="text" name="name">
            </label>
        </p>
        <p>
            <button>Create</button>
            <button formmethod="dialog" formnovalidate>Cancel</button>
        </p>
    </form>
</dialog>

When the cancel button is pressed, this will issue a request contrary to browser behaviour.

You just use hx-boost="false" on the dialog

There was a recent-ish related issue on the topic of formmethod="dialog" (#1866), not specific to boosted forms. The linked pull request changed the way HTMX handles it by having it send a POST request rather than an invalid DIALOG request. While that is an improvement of sorts, I think it would be more intuitive to follow the spec and close the dialog without sending a request.
