// 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 `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. |
// |
// See https://github.com/twbs/bootstrap/pull/12794 and |
// https://github.com/twbs/bootstrap/pull/14559 for more information. |
