Keep the HTML in Popover when it isn't open

[charklewis]

I am using the Popover element with a form and wanting to see how I could keep the Popover.Panel in the HTML when the popover isn't shown. The issue I have is when I close the popover, the inputs in the panel unmount from the DOM so when the form is submitted they are missing.

Understandably I could store the values of the inputs somewhere, but looking to see if I can just keep the HTML in the DOM.
