Done

This is a no-go hack:
those customItems shouldn't be reparented, but rather the property should be an alias to the data of another layout, like:

property alias customItems: innerLayout.data
contentItem: RowLayout {
    id: rowLayout
    RowLayout {
        id: innerLayout
    }

or, i would prefer even more, to just ditch that extra property completely:

default property alias _contents: rowLayout.data
contentItem: RowLayout {

​ id: rowLayout
​ Heading {

....

so one just does

ListSectionHeader {
   Button {....}
}

and just works(tm)
