/** 
 * @description Test for Bug 41339 - unicode-range property only with a
 * descending range causes a crash
 * Interval unicode-ranges that descend are invalid and omitted. Without any
 * valid ranges, the descriptor is omitted. As a result, the @font-face rule in
 * this file is applied to all characters. This test passes if the following
 * i's and X's are shown in Courier and they have the same length on screen. As
 * of r62096, opening this file causes a crash instead.
