Bug ListView Bind ArraySize+Scroll Bug

In

Code (CSharp):

1. ListView:OnScroll(float offset)

this part (line:1460)

Code (CSharp):

1. for (var i = 0; i < m_Pool.Count; i++)
2. {
3.     int index = i + m_FirstVisibleIndex;
4.     if (index < itemsSource.Count)
5.         Setup(m_Pool[i], index);
6.     else
7.         m_Pool[i].element.style.display = DisplayStyle.None;
8. }

m_FirstVisibleIndex could be -1 when SerializedProperty:ArraySize is bound.
and the ListViewBinding will try to bind ArrayElementAt(-1) and result in an index exception.
Using the first element of ListView::ScorllView is a bad idea.
We may let ListView to have a contentContainer
so we can put size field, add/remove item button and info label in it.

 

Also when reorder is enabled.
when dragging ListView size item to the bottom of the list an index exception will be throwing.
and It is also because bind-size-as-a-List-Item design.
