I'm increasing it to 100MB to make sure, any bootloader will fit with all its stages. Of course, right now the reason why GRUB doesn't fit into the partition is because of mdadm 3.3.2 and thus the initrd taking all the space, but in order to avoid confusion on why the *boot* loader fails in the VM tests, I've increased the size.
