How to vertically align text in a WebTextEditor control? There is a property "HorizontalAlign" for alignment in horizontal dimension, but there is no property for vertical alignment!?

I have already tried

style="vertical-align:middle;"

Setting this style attribute obviously does not have any effect! I can set to "top, buttom, text-top, text-buttom" or any other value - the text inside the control is always aligned on top!!!

So is there really no way to vertically align text in a WebTextEditor control???
