Unable to run `Memory Test` from Grub's boot menu: `error: file /boot/Memory not found`

I think it is the known issue:

Memory Test no longer included on live ISOs?

I just booted the latest XFCE and Cinnamon ISOs to run the Memory Test. It still shows up as an option in the Grub menu, but when you select Memory Test it says, “error: file ‘/boot/Memory’ not found”. Is this a packaging error and should Memory Test be on the ISOs or should the option be removed from the Grub menu?
