TextFlow: How can I reduce the gap between ListItemElements in Adobe Air Mobile 19

Hi,

I've got a textFlow imported with TextConverter.importToFlow(htmlValue, TextConverter.TEXT_FIELD_HTML_FORMAT);

The gap between the ListItemElements produced with <ul><li>Item1</li><li>Item2</li></ul> is too big. I've tried many things to reduce the gap height, with no luck.

What I've tried:

      var arr:Array = label1.textFlow.getElementsByTypeName("li");

for each(var listElement:ListItemElement in arr){

                    var pArr:Array = listElement.getTextFlow().getElementsByTypeName("p");

                    for each(var p:ParagraphElement in pArr){

                        TextLayoutFormat(p.format).paddingBottom = -100;

                        TextLayoutFormat(p.format).paddingTop = -100;

                        TextLayoutFormat(p.format).listAutoPadding = 0;

                        TextLayoutFormat(p.format).lineHeight = "100%";

                        var spanArr:Array = listElement.getTextFlow().getElementsByTypeName("span");

                        for each(var span:SpanElement in spanArr){

                            TextLayoutFormat(span.format).paddingBottom = -100;

                            TextLayoutFormat(span.format).paddingTop = -100;

                            TextLayoutFormat(span.format).listAutoPadding = 0;

                            TextLayoutFormat(span.format).lineHeight = "100%";

                        }

                    }

                    TextLayoutFormat(listElement.format).lineHeight = "105%";

                    TextLayoutFormat(listElement.format).paddingBottom = -200;

                    TextLayoutFormat(listElement.format).paddingTop = -200;

                }

The only effect is that the lineHeight inside the ListItemElement is rededuced which is not the expected behavior.

Do you have any ideas??

Thanks in advance.
