[]部分字体在Runtime下描边效果失效

是不是因为没有字体库导致的？没有字体库切换到默认字体也就没了

               Font.defaultFamily = "DFHeiW5-A";   // 屏蔽掉这个就可以正确显示
                // 系统自带
                var txt:Text = new Text();
                txt.fontSize = 18;
                txt.text = "角色名10920-";
                txt.color = "#ffffff";
                txt.stroke = 2;
                txt.strokeColor = "#000000";
                txt.x = 350;
                txt.y = 220;
                Laya.stage.addChild( txt );
