No, it does not.  Installing grub to the wrong place because you
manually chose it is not a bug.  Installing grub to /dev/sda by
default when your computer actually boots from another drive is also
not a bug, because unfortunately, there simply is no way to detect
which drive the computer boots from due to the limitations of the pc
bios.  If grub outright failed to install, then there *may* be a bug.
 The installer automatically files a bug report when this happens so
it can be investigated.

"Never happen no matter what" is asking for a magic wand and unicorns.
 There are some things we can control, and some we can not.

Title:
  Ubuntu 14.04 Update breaks grub, resulting in "error: symbol
  'grub_term_highlight_color' not found"

Status in “grub2” package in Ubuntu:
  Triaged

Bug description:
  The update from 13.10 to 14.04 via update-manager broke grub for me,
  which resulted in the grub error:

  "symbol 'grub_term_highlight_color' not found"

  on startup.

  To fix the problem I had to boot to my persisting Ubuntu installation
  (e.g. using Super Grub Disk) and had to reinstall grub on my boot
  partition: "sudo grub-install --recheck /dev/sdx"
