Loopback boot not working in 5.1 Hera

[howl]

I know is not a bug in the installer itself but I don't know where to report live media issues If someone point me into the right direction thanks in advance.

I boot elementary iso from a usb using grub loopback booting, it works in elementary as is ubuntu, but the last release 5.1 doesn't try to find the iso file so is not possible to boot it this way. Seems to be an issue in initrd because initial ramdisk is where the boot option is processed to allocate the iso. Ubuntu 18.04.3 LTS is able to boot using loopback.

Still present in 5.1.2.

Same in 5.1.3 that I forget to report, and also the same with 5.1.4.

Is this going to be fixed for Hera minor versions?

Equal in 6.0 Beta. Seems it's not going to be possible to use this feature in Elementary.

This seems fixed since 7.0 as 7.0 and 7.1 can be loopback booted, but, in loopback.cfg findiso= is used to do that where the working one is iso-scan/filename=.
