 * remove the element from the accessibility tree and that
 * `display: none` and `visibility: hidden` are not focusable.
 *
 * The target stays visible if any element within receives focus through keyboard.

/*
 * Remove space when hidden.
 * 1. Remove from document flow.
 * 2. Hide element and shrink its dimension. Current browsers and screen readers
 *    keep the element in the accessibility tree even with zero dimensions.
 *    Using `tabindex="-1"` will show the element on touch devices.
 *    Note: `clip-path` doesn't work with `tabindex` on touch devices.
