By luck and 14 years of xorriso development. :))
Can i talk you into a second test ?
This time only disable the part in grub.cfg which evaluates the variable:
if [ "$grub_platform" = "efi" ]; then
menuentry 'Boot from next volume' {
exit
}
but leave the command in effect:
grub_platform
The resulting behavior will be of interest when asking GRUB experts for an
explanation.
-------------------------------------------------------------------------
We still could need to know what wonder exactly gnome disks does for
Lucap.
Somehow the partition table of the ISO influences the ability of
command and/or variable evaluation to do its job in reasonable time.
The proposed xorriso runs will hopefully show what exactly lets
grub_platform or the evaluation of $grub_platform block boot progress.

When both open questions are answered, it will be time that Ubuntu ISO
production takes this case to one of the mailing lists about misbehaving
GRUB. Let's have a look into the archives.
Not much replies:
https://lists.gnu.org/mailman/listinfo/bug-grub
Probably not the right audience:
https://lists.gnu.org/mailman/listinfo/help-grub
Quite oriented to "[PATCH]"-work. But at least they discuss what is posted:
https://lists.gnu.org/mailman/listinfo/grub-devel/
I am subscribed to grub-devel, because of grub-mkrescue. So i could serve
as curious bystander who wonders where command grub_platform is
implemented.
Have a nice day :)
