Potential Bug with Layout containing Repeater inside ScrollView with 6.5.3?

antiocles

Just updated a project from 6.3 to latest LTS 6.5.3 and discovered my dynamically added content was no longer sizing the scroll area anymore. Seems maybe unintentional? In my actual application, the model is a true dynamic model and not just a simple repeat, but luckily both exhibit it.

//item inside a layout, but think it can be anywhere
            Item {
                Layout.fillWidth: true
                Layout.fillHeight: true

                ScrollView {
                    id: buttonScrollView
                    anchors.fill: parent
//uncomment here to function fine on 6.5.3, worked fine in 6.3 and earlier...
                    //contentHeight: assignmentLayout.childrenRect.height
                    //contentWidth: assignmentLayout.childrenRect.width
                   
                    ColumnLayout {
                        id: assignmentLayout
                        width: parent.width
                        Repeater {
                            model: 10
                             Label {
                                    text: "ABC"
                                   font.pixelSize: 100
                              }
                        }
                    }
                }
            }

If you change it to just be 10 static items in the ColumnLayout, works fine. Only when being added by a repeater does the issue show.

I tested with any layout, and they all behave the same. Can be fixed by adding contentHeight: assignmentLayout.childrenRect.height and similar, but that was not necessary before so not sure which is the intended behavior. Bug I think?
