The pdf document viewer is displayed, but the document itself is not loaded into the viewer or displayed under all but the first tab on a wiki page. For example, when using the either the Header Tabs or Tabs extension, the document viewer is displayed and the document loads under the first tab only. In all subsequent tabs, only the viewer is displayed. In this situation, if the viewer is configured other than default (e.g., change page <pdf page=2>), the viewer is blank and still indicates page 1/1. By clicking the resize button on the viewer, the document then loads and displays correctly.
Is there a way to force the viewer to load and display the document when the markup code (i.e., <pdf></pdf>) is processed?
