ListView in Column item requires anchors. Item's y property ignored.

Hi,
I believe I have discovered 2 bugs, see the attached file:
1. Line 176: the parent of this ListView is a Column, so in theory the ListView should not require an anchors property. However, if I comment this line, there is no list, only one element is shown, badly formatted.
2. Lines 167, 168: the y property seems to be ignored. No matter what values I put there, the y value seems to be ignored.

I am new to QML, so I might just do something wrong here.
