Описание

Сейчас есть проблема, что при отключенном разделителе(delimiter="none"), при float={true} и при прозрачной панели(transparent={true}) все равно отображается разделитель, который наезжает на контент и портит вид.

Изменения

Добавил проверку на отсутствие селектора .trnsp при отрисовке разделителя.

Release notes

Исправления

• PanelHeader: отключен разделитель при прозрачном PanelHeader и delimiter="none"
