Description
When rendering multiple items (label, text, input...) within a TreeView with delegates, the performance becomes very slow. The view starts stuttering on scroll and collapsing branches take long time.
For a workaround we found a change to TreeViewItemDelegateLoader.qml add a null data value can solve this issue
