/**
 * Known issues:
 * - `select`:
 *   By default, Chrome on OS X and Safari on OS X allow very limited styling of
 *   select, unless a border property is set. The default font weight on
 *   optgroup elements cannot safely be changed in Chrome on OSX and Safari on
 *   OS X.
 * - `[type="checkbox"]`:
 *   It is recommended that you do not style checkbox and radio inputs as
 *   Firefox's implementation does not respect box-sizing, padding, or width.
 * - `[type="number"]`:
 *   Certain font size values applied to number inputs cause the cursor style of
 *   the decrement button to change from `default` to `text`.
 * - `[type="search"]`:
 *   The search input is not fully stylable by default. In Chrome and Safari on
 *   OSX/iOS you can't control `font`, `padding`, `border`, or `background`. In
 *   Chrome and Safari on Windows you can't control `border` properly. It will
 *   apply `border-width` but will only show a border color (which cannot be
 *   controlled) for the outer 1px of that border. Applying
 *   `-webkit-appearance: textfield` addresses these issues without removing the
 *   benefits of search inputs (e.g. showing past searches). Safari (but not
 *   Chrome) will clip the cancel button on when it has padding (and `textfield`
 *   appearance).
 * - `::placeholder`:
 *   In Edge, placeholders will disappear on `relative` or `absolute` positioned
 *   `<input>` elements if you use `opacity` less than `1` due to a
 *   [bug](https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/3901363/).
