Bug: Escaping Popover shows aria-hidden error in the console

[anastasialanz]

Steps to reproduce

• Go to https://cauldron.dequelabs.com/components/Popover
• Open the browser's developer tools
• Click on the "Prompt!" button
• Press esc
• See that the console shows Blocked aria-hidden on a <button> element because the element that just received focus must not be hidden from assistive technology users. Avoid using aria-hidden on a focused element or its ancestor. Consider using the inert attribute instead, which will also prevent focus. For more details, see the aria-hidden section of the WAI-ARIA specification at https://w3c.github.io/aria/#aria-hidden.
