+  // information about what media items were selected. However, Drupal UI
+  // convention is to place all action buttons on the same "line" at the bottom
+  // of the form, so if the form within the IFRAME contains a "Submit" button or
+  // other action buttons, then the "OK" button will appear below the IFRAME
+  // which breaks this convention and is confusing to the user. Therefore, we
+  // add a "Submit" button inside the IFRAME, and have its click action trigger
+  // the click action of the corresponding "OK" button that is outside the
+  // IFRAME. media.css contains CSS rules that hide the outside buttons.
+
+  // If a submit button is present, another round-trip to the server is needed
+  // before the user's selection is finalized. For these cases, when the form's
+  // real Submit button is clicked, the server either returns another form for
+  // the user to fill out, or else a completion page that contains or sets the
+  // Drupal.media.browser.selectedMedia variable. If the latter, then
+  // Drupal.media.popups.mediaBrowser.mediaBrowserOnLoad() auto-triggers the
+  // "OK" button action to finalize the selection and remove the IFRAME.
+
+  // We need to check for the fake submit button that is used on non-form based
+  // pane content. On these items we need to bind the clicks so that media can
+  // be selected or the window can be closed. This is still a hacky approach,
