html works for flash but not air

My code works when I publish as a flash player file but not an air app. What would be the workaround? Is there some kind of security issue?

import flash.text.TextField; var labelText:String = '<img class="aligncenter size-full wp-image-35505" src="https://www.onelittledaisy.co.uk/wp-content/uploads/CeriStacey-001.jpg" alt="" width="900" height="600" />'; var label:TextField = new TextField(); label.border = true; label.multiline = true; label.wordWrap = true; label.width = 900; label.height = 600; addChild(label); label.htmlText = labelText;
