      Description

      If a QQC TableView has more entries than its height would fit, the Repeater in the Column with the id: rowfiller in the BasicTableView.qml calculates a negative model size which results in error messages like:

      Model size of -1 is less than 0

      This can be tested with a minimal example:

      // main.qml
      import QtQuick 2.15
      import QtQuick.Window 2.15
      import QtQuick.Controls 1.4 as QQC
      
      Window {
          width: 640
          height: 80
          visible: true
          title: qsTr("Model Size Issue")
      
          QQC.TableView {
              anchors.fill: parent
      
              model: ListModel {
                  ListElement { name: "Row 1" }
                  ListElement { name: "Row 2" }
                  ListElement { name: "Row 3" }
                  ListElement { name: "Row 4" }
                  // add/remove elements beyond the 4th to get the error message
                  ListElement { name: "Row 5" }
              }
      
              QQC.TableViewColumn {
                  role: "name"
                  title: "Rows"
              }
          }
      }
