/**
 * Avoid 300ms click delay on touch devices that support the `touch-action`
 * CSS property.
 *
 * In particular, unlike most other browsers, IE11+Edge on Windows 10 on
 * touch devices and IE Mobile 10-11 DON'T remove the click delay when
 * `<meta name="viewport" content="width=device-width">` is present.
 * However, they DO support removing the click delay via
 * `touch-action: manipulation`.
 *
 * See:
