This feature would add support for the <dialog> element to create in-page modal windows.
The dialog element is now on the backlog with a priority of medium. You can track status changes at https://dev.modern.ie/platform/status/dialogelementformodals/

This has the potential to be a good replacement for the showModalDialog() command. We have an enterprise application written in asp.net that relies heavily on this command for popup windows. The HTML 5 dialog command could give us equivalent functionality... much like an iframe.
Our web app was started nearly 10 years ago, and uses showModalDialog() in a bunch of screens, we sell into corporates, and now that we're pretty much HTML5 compliant, we're the ones telling them to upgrade from IE7,8,9 - but they have other web apps that prevent them. The fact that Firefox deprecates showModalDialog and Chrome doesn't support it at all is not such a problem for us, except customers do want to use other browsers (on tablets etc) We have third party solutions (Telerik) etc but it would be nice to have one standard method for client-side dialog invocation.

Seeing as showModalDialog() is deprecated, this is definitely needed.

This is long overdue, do the right thing & have it released please!

Blink implements it and allows us to provide a much better user experience, otherwise we are down to confirm() which sucks or rolling our own.
Absolutely want this for the future !
