[nautilus/antoniof/goodbye-morphing-pathbar] toolbar: Always show pathbar background

    toolbar: Always show pathbar background
    
    We hide the pathbar background when the window is small enough that
    the pathbar is no longer centered. This was introduced to make the
    pathbar flat.
    
    However, now that the pathbar is buttonized again, it doesn't make it
    flat, so there is no point. Also, the transformation is surprising.
    Furthermore, it is prone to styling glitches.
    
    So, give up on the transformation and always have a pathbar background,
    effectively reverting commit 080400bd243ab86d82954eaff0c866c3ac97f3f2
