min_extents and max_extents mangled with Python interface

[gregfi]

I'm attempting to use the Python interface to write a new Silo file that contains modifications to an existing Silo file. I'm using Python 3.11 and Silo 4.11.1. My code looks something like the following:

importedSilo = Silo.Open('input.silo', Silo.DB_READ)
outputSilo = Silo.Create('output.silo', 'test_output', Silo.DB_HDF5, Silo.DB_CLOBBER)   

mesh = importedSilo.GetVarInfo('mesh', 1)
outputSilo.WriteObject('mesh', mesh)

importedSilo.Close()
outputSilo.Close()                                                             

When I inspect the input and output data sets, for the min_extents and max_extents metadata, I see:

INPUT SILO:
  min_extents: (0.0, 0.0, 0.0)
  max_extents: (126.88, 6.283185307179586, 443.0)

OUTPUT SILO:
  min_extents1: 0.0
  min_extents2: 0.0
  min_extents3: 0.0
  max_extents1: 126.88
  max_extents2: 5.79923737063e-313
  max_extents3: 1.230757558913e-312

Is there a way to preserve min_extents and max_extents data?
