How to Align Rich Text Vertically
Some users have reported that the vertical-alignment style attribute for rich text does not function properly.
Reports mention that after specifying this attribute, the text does not properly adjust itself to the vertical alignment of the text render extension that it is contained in.
If we take a look at the documentation for this option it is described as:
