 * Sets the visibility of focus styling.
 *
 * By default, focus styles (the box surrounding a focused Button, for example) only show up when navigational
 * keypresses occur (through Tab, arrows, PgUp/PgDn, Home and End), and are hidden when mouse interactions occur.
 * This API provides an imperative way to turn them on/off.
 *
 * A use case might be when you have a keypress like ctrl-f6 navigate to a particular region on the page,
 * and want focus to show up.
 *
 * @param enabled - whether to remove or add focus
 * @param target - optional target
