Table Captions not rendering correctly when using CKEditor WYSIWYG

Table caption is incorrectly displayed when page is saved in new wiki. I updated a table in WYSIWYG mode, and added a table caption using the Table Properties dialog box. The WYSIWYG displayed fine, with the caption appearing immediately above the table. However, when I saved the page, the caption appeared in the first table cell prepended to the text that was in that cell. When I reopened for editing, the text was in the cell, and the Table Properties dialog no longer showed any caption text.
