// Checkbox and radio options

// use `display: none;` or `visibility: hidden;` as that also hides the popover.

// Simply visually hiding the inputs via `opacity` would leave them clickable in
// certain cases which is prevented by using `clip` and `pointer-events`.
// This way, we ensure a DOM element is visible to position the popover from.
