Commented Unassigned: Cell RichText collection not initial empty [15374]

When using ExcelRangeBase.RichText, when the ExcelRangeBase is a single cell, the first cell works fine. However, the second cell you set initially gets a copy of the previous cell's content. When you call ExcelRichTextCollection.Add, the content is added to the copy from the first cell.

Fortunately, calling ExcelRichTextCollection.Clear is an easy workaround.
