Keeping a dialog mounted in the DOM

[pjsachdev]

Thank you for creating such a brilliant library!

Is there a way to have the dialog component mounted in the DOM for SEO reasons whilst it is closed? Would showing and hiding the dialog with CSS have an impact on the a11y?

Material UI has a prop of keepMounted on their modal component - https://mui.com/material-ui/api/modal/

Something similar would be ideal for react-aria-components
