Follow-up Comment #3, bug #37812 (project avrdude):

This is a bug in the Arduino bootloader, and you should report it
accordingly.
Sure, the bootloader is not supposed to actually perform a chip erase
(and a bootloader even has no means to do that at all), but it must
perform the best approximation of a chip erase, that would mean to
erase *all* application pages when being asked to erase the chip.
Everything else is asking for trouble.
Unfortunately, the STK500v2 command doesn't offer any means of erasing
just a page only (for non-Xmega devices), which is basically due to
the fact that there is no "page erase" ISP command. That's the reason
why AVRDUDE cannot perform page erases here.
