The recipient list (in CC in this case) is truncated (actually rather "hidden" than truncated) and the "more" button is not shown. If I minimise the "today" pane, the list is shown correctly with the "more" button at the end. However, it has nothing to do with the today pane - if I minimise the today pane but then resize the TB window to be smaller the recipient list is again truncated. It may have something to do with the Arabic characters. Reproducible: Always Steps to Reproduce: 1. Preview a mail with a long list of recipients, preferably with Arabic characters 2. 3. Actual Results: The recipients list is truncated (hidden) Expected Results: The "more" button should be shown after a couple of recipient names. The "more" button is there, but hidden behind other elements, will become visible if the TB window is resized to be large enough.
