HTML5 summary and details tags

[Aterniad]

Hi!
Once input had <summary> and <details> HTML5 tags I immediately got an error: "Element 'details' is not supported (for information on implementing this, see the support forums)"

As your docs say, I've fixed it in the following way:

class Html5Definition extends \Stevebauman\Purify\Definitions\Html5Definition
{
    public static function apply(\HTMLPurifier_HTMLDefinition $definition)
    {
        parent::apply($definition);
        $definition->addElement('summary', 'Block', 'Flow', 'Common', [
            'open' => 'Bool',
        ]);
        $definition->addElement('details', 'Block', 'Flow', 'Common');
    }
}

Specifications:

Would be rather cool to have this working out of box ;)

Thanks for the info @Aterniad! Would you mind pushing a PR and making these additions to the Html5 definition here?

These fall under Interactive Elements: https://html.spec.whatwg.org/dev/interactive-elements.html. They include summary, details and dialog, all of which need to be added.

@Aterniad I can make this PR if you don't have time.
