autoFocus input not working within dialog

[SamKirkland]

When using <input autoFocus /> within a modal the input will not be focused because the modal captures focus.
See library code examples or live examples

Appears to be due to focus capture implemented on first render

dialog/src/Dialog/Content/Panel.tsx

Line 56 in 4f70824

sentinelStartRef.current.focus();

It might make sense to switch to dialog instead https://developer.mozilla.org/en-US/docs/Web/HTML/Element/dialog as browser support is solid https://caniuse.com/?search=dialog
