The layout of lines in a RichTextBox element is affected by this property and by the LineStackingStrategy property. This property is used to set the height of each line containing text when LineStackingStrategy property is set to BlockLineHeight or BaselineToBaseline. When LineStackingStrategy property is set to MaxHeight, the larger of calculated LineHeight or set value of LineHeight property is set as the LineHeight.
If LineHeight properties of a RichTextBox and its Block element differs, the LineHeight property of the Block will be honored.
