[Bug 1964719] [NEW] GRUB shows up by default, even though GRUB_TIMEOUT=0

[Jonas Gamao]

Public bug reported:

Here's my GRUB config:
GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

It's annoying that it keeps showing up by default because it's only
Kubuntu on this laptop.
