Add a title to the generate iframe

[mark-making]

To ensure an accessible web, and for the sake of passing accessibility audits, please can we set the title for the generated iframe? Looking through the code it would be similar to how the id is set.

iframe.id = "netlify-identity-widget";

iframe.title = "Netlify identity widget";

Chrome's Lighthouse tab made me aware of this issue. I solved this in my Vue app with a simple check that seems to be working for me:

// in main.js
import netlifyIdentity from 'netlify-identity-widget';

let netlifyIdentityWidgetIframe = document.getElementById('netlify-identity-widget');

if (!netlifyIdentityWidgetIframe) {
  netlifyIdentity.init();
}
