SplitButton with custom ItemTemplate - Source change does not always update layout #3017
Description
For example, I install a source with 1 element, then I reset it and install it with 3 elements. In this case, the control is not redrawn, and shows only 1 element, although there are 3 of them.
splitButtonPlay.ItemsSource = null; splitButtonPlay.ItemsSource = buttonList;
