Summary

WebScrollView.EnsureVisible doesnot work on selecting row from WebListBox

Type             : Bug
Priority         : Medium
Gambas version   : Master
Product          : Web components


Description
-----------

I have a WebScrollView which contains a WebListBox and two other controls

WebListBox1.Height = "13em"
WebListBox1.List = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"] 

When I scroll WebListBox and select an item and want to show third control

Public Sub WebListBox1_Select()

  WebTextArea2.Text = WebListBox1.Text
  WebScrollView1.EnsureVisible(WebTextArea2)

End

The third control is not visible. Moreover the WebListBox is refreshed and WebListBox.Selection is removed.
