When applying Optimal row height (and wrap text = on for relevant cells), the height gets changed automatically. But after changing column width (and as a consequence the vertical space needed for the text changes), row height is not applied automatically. As a consequence, text disappears (and a red triangle is displayed) or white space is visible.

I expect the row height to be adjusted if the column width is changed (for relevant cells)
