Bug in AbsoluteOptions, PlotRange when Using an Arrow

I believe there is a bug in AbsoluteOptions for PlotRange when the PlotRange
is determined by an Arrow. Here are two different cases using first an Arrow
and then a Line instead of the Arrow. Correct results are obtained for the
Line and incorrect results are obtained for the Arrow.

 

plot1 =

 Graphics[

  {Arrow[{{0, -1}, {0, 0}}], AbsolutePointSize[6], Point[{-1, 0}], 

   Point[{1, 0}]},

  PlotRange -> All,

  Frame -> True]

AbsoluteOptions[plot1, PlotRange]

 

plot1=

Graphics[

{Line[{{0,-1},{0,0}}],AbsolutePointSize[6],Point[{-1,0}],Point[{1,0}]},

PlotRange->All,

Frame->True]

AbsoluteOptions[plot1,PlotRange]

 

plot2 =

 Graphics[

  {Arrow[{{0, -1}, {0, 0}}]},

  PlotRange -> All,

  Frame -> True]

AbsoluteOptions[plot2, PlotRange]

 

plot2 =

 Graphics[

  {Line[{{0, -1}, {0, 0}}]},

  PlotRange -> All,

  Frame -> True]

AbsoluteOptions[plot2, PlotRange]
