This is why I mainly use some other custom <div> with a popover="" attribute. They're easily targeted with a button and no clientside JS required, and can be closed by clicking outside them, which <dialog>s don't have by default. They also still have the same helpful top-layer properties.

Unsure about accessibility on this front, though it can't be worse than my previous attempts with hidden labels/checkboxes/form elements, while being much simpler and less hacky.

Re. accessibility, the main feature is that dialogs can be "modal" - meaning the rest of the page is non-interactive while the dialog is open - ensuring a focus trap.

Popovers are always non-modal, which can be problematic depending on the use-case. Of course it's possible to manually implement a focus trap, but it's complex and it's javascript.

Yes, I wish when the popover attributes were created there was something included for opening a modal dialog.

I think it is possible to use popover to open a dialog non-modally and use progressive enhancement to replace that behavior with `.showModal()`.
