    tdf#143239 sw: layout: invalidate fly position when moving off page
    
    It's possible that flags on the fly are all valid when it is moved off page
    when SwLayAction::FormatContent() returns and then it may not be positioned
    again, keeping its (wrong) position on the old page and will appear to be
    invisible unless you click on it.

    Fix flaky test on Win64
    
    Obviously the left values are unstable; they were excluded on macOS,
    and they fail exactly on the same lines for me locally on Win64 build.
    So just test that the values are restored after delete and undo.
