public CaptionRectangle withHeight(Double height) {
        setHeight(height);
        return this;
    }
See the description in leftOffset. For height, specify the entire height of the rectangle as a percentage of the
underlying frame height. For example, \"80\" means the rectangle height is 80% of the underlying frame height.
The topOffset and rectangleHeight must add up to 100% or less. This field corresponds to tts:extent - Y in the
TTML standard.
