 * The main purpose of this is to allow web developers  to style DOM elements based on
 * the size of a containing element rather than the size of the browser viewport.
 *
 * @param {QueryBreakpoints} breakpoints A key/value mapping of explicit breakpoint ranges to be
 * tested against the current observed elements width to find a match.
 * @param {boolean} ignoreDimensions Flag stating the user doesn't care about the changing container width,
 * and only the breakpoint changes. The app will only update state on these changes.
