After installation anaconda-ks.cfg stores wrong record of disk layout when percentage used

Issue

• When using in kickstart:

  part /boot --fstype=ext4 --size=256 --asprimary --ondisk=$ondisk
  part pv.2 --size=1 --grow --asprimary --ondisk=sda
  volgroup vg_root pv.2
  lv_snapshot_space to allow cleanup in post
  logvol /snapshot_space --fstype=ext4 --name=lv_snapshot_space --vgname=vg_root --percent=10 --grow --size=1
  

• anaconda-ks.cfg was written with:

  # The following is the partition information you requested
  # Note that any partitions you deleted are not expressed
  # here so unless you clear all partitions first, this is
  # not guaranteed to work
  #clearpart --all --drives=vda --initlabel
  
  #part /boot --fstype=ext4 --asprimary --size=256
  #part pv.253002 --grow --asprimary --size=1
  #volgroup vg_root --pesize=32768 pv.253002
  #logvol / --fstype=ext4 --name=lv_root --vgname=vg_root --grow --size=1
  #logvol /snapshot_space --fstype=ext4 --name=lv_snapshot_space --vgname=vg_root --grow --size=1
  #logvol swap --name=lv_swap --vgname=vg_root --size=2048
  

• Note the missing percent for /snapshot_space
