+   *
+   * Note:
+   * Avoid using margins on the observed element. The calculation can return incorrect values when margins are involved.
+   *
+   * The following CSS will report incorrect width (Chrome OSX):
+   *
+   * <div id="outer" style="width: 300px; height:300px; background-color: green;overflow:auto;">
+   *   <div id="observed" style="width: 400px; height:400px; background-color: yellow; margin:30px; border: 20px solid red; padding:10px;">
+   *   </div>
+   * </div>
+   *
+   * The calculated width is 280. The actual (correct) width is 340 since Chrome clips the margin.
+   *
+   * Use an outer container if you really need a "margin":
+   *
+   * <div id="outer" style="width: 300px; height:300px; background-color: green;overflow:auto; padding:30px;">
+   *   <div id="observed" style="width: 400px; height:400px; background-color: yellow; margin: 0; border: 20px solid red; padding:10px;">
