In this situation, the Adjust height to fit zone setting of the Report Viewer Web Part isn't respected. For example, when you open the SharePoint webpage that contains the Report Viewer Web Part, only part of the report is showed up inside the Report Viewer Web Part. Then, if you refresh the webpage, more report content is displayed.
