Nested Popovers no longer work on version 1.7.8

[alex-ketch]

Encountered this just now and seems like the discussion should be an issue instead.
Can try and investigate sometime over the coming weekends if desired.

Discussed in #2221

Summary

With the latest update of 1.7.8, when using React 17, Popovers inside another Popover's Panel don't have IDs on the buttons, which makes them unable to open the next level down

"react-dom": "^17.0.1",
"@headlessui/react": "1.7.8"
