Title:
Header should only change flickable content margins when its size is
not null and it's visible property is true
Status in Canonical System Image:
New
Status in ubuntu-ui-toolkit package in Ubuntu:

Bug description:
r1886
Header should not update (or it should stop updating) Flickable content
margins in case either one (or both) of its sides has null size or it's
!visible.
This is to be consistent with how QtQuick layout components already behave ->
they ignore children whose size is null or that are !visible.
NOTE: opacity should not affect this logic. If opacity is 0, the items
should NOT be ignored (this allows opacity animations).
TestCase: you can verify that flickable.topMargin is equal to
editHeader's height even when the header it's not visible and
standardHeader is the visible one instead.
