I re-checked grub2 manual for 2.00 and it explicitly says that
item_height is in pixel; it lists several properties for which support
for proportional units is explicitly stated. So either you are using
different manual (coming from your distribution?) or probably
misunderstood it. In which case it would help if you suggested
corrections that make it more clear.

I guess that grub simply ignored '%' and interpreted value as absolute
one.

Or your grub does support proportional units for item_height indeed,
then it is distribution-specific patch.
