Feature Request - Add Dialog polyfill

[JamesCoyle]

The dialog element is now defined in the HTML 5.2 specification. It is a really useful element that everyone should be using for modal elements as it has many benefits for accessibility and prevents any annoying z-index issues.

Can a polyfill be added for browsers that do not yet implement it? I believe this is the defacto polyfill for the dialog element: https://github.com/GoogleChrome/dialog-polyfill

We can't implement a polyfill for dialog as it also requires adding CSS to the page to polyfill the dialog's design which is something polyfill-library and polyfill.io do not support.
