 // Checkbox and radio options

+// In order to support the browser's form validation feedback, powered by the
+// `required` attribute, we have to "hide" the inputs via `opacity`. We cannot
+// use `display: none;` or `visibility: hidden;` as that also hides the popover.
+// This way, we ensure a DOM element is visible to position the popover from.
+//
