  195. // `display: none;` or `visibility: hidden;` as that also hides the popover.
  196. // Simply visually hiding the inputs via `opacity` would leave them clickable in
  197. // certain cases which is prevented by using `clip` and `pointer-events`.
  198. // This way, we ensure a DOM element is visible to position the popover from.
