-// In order to support the browser's form validation feedback, powered by the
-// `required` attribute, we have to "hide" the inputs via `clip`. We cannot 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.
