[5.x] form.renderClosingTag() has no way to pass in properties

[rob-c-baker]

With this:

{% set properties = {
    buttons: {
        attributes: {
            submit: { class: "'button is-primary'" },
            buttonWrapper: {
                class: 'buttons'
            },
        },
        submitLabel: "Save"
    }
} %}

The documentation talks about things like this:

{{ form.render(properties) }}

But with a custom form rendering template, that may never be called, instead it's generally more like:

{{ form.renderTag(properties ) }}
    [ form elements]
{{ form.renderClosingTag() }}

The problem I'm having is with the latter, custom twig rendering template, the buttons property overrides do not take effect and there is no opportunity to pass properties into {{ form.renderClosingTag() }}.

Is there a way around this?

Doh!

I had made a mistake here:

submit: { class: "'button is-primary'" }, should be submit: { class: "button is-primary" }.

Closing.
