Hmm okay, and it's grub-pc. I'll try to reproduce this myself as well.

Title:
  Wrong defaults after (deprecated) changes: #GRUB_TIMEOUT_STYLE

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  #GRUB_TIMEOUT_STYLE=hidden 
  has been default setting for at least a decade, also here on my various machines with multiple OSes. It did work in a reasonable manner: (wiki.ubuntuusers.de/GRUB_2/Konfiguration) "Die Einstellung hidden bzw. countdown wird ignoriert und das GRUB-Menü immer angezeigt, wenn mehr als ein Betriebssystem von GRUB verwaltet wird." (With more than one OSes being bootable through grub, the setting 'hidden' will be ignored).
  This made sense for single OSes (no need to show, and if, with Esc), as well as with multiple OSes (showing the OS that is going to come up). With my recent update (release), suddenly no more grub menu showed. 
  According to https://askubuntu.com/questions/1526795/grub-menu-doesnt-show-any-longer one had to set this grub variable to "menu". Immediately the grub menu popped up again. 
  All the hassle around this would have been unnecessary without the changed behaviour of grub with the identical variable. (While this change could be questioned, this is not my concern here.)

  It is an unnecessary bug behaviour to change items with the identical
  parameter. For security and user convenience, either the grub default
  ought to have been set to the 'safe' (no loss of OS) value of "menu",
  or a new parameter introduced; keeping the behaviour of existing
  parameters as such (and eventually only withdrawn after extended times
  of deprecation, if at all).
