Text wrapping using Vaadin ComponentFactory Tooltip

Flow
1

I am seeing inconsistent wrapping behaviour using the ComponentFactory Tooltip. I have a simple method to create a Tooltip

 public static Tooltip makeTooltip(String mainText,  TooltipPosition t)
    {
        Tooltip tooltip = new Tooltip();
        tooltip.setPosition(t);
        Paragraph p1 = new Paragraph();
        p1.getElement().setProperty("innerHTML",mainText);
        tooltip.add(p1);
        return tooltip;
    }

I have applied to a component on a Person Form and a component on a Card List), using the V19 starter App. The tooltip wraps correctly on the form, but does not wrap on the Card. - see image uploaded.
