Ubuntu 22.04 - x86-64, does it, see below

Raspberry PI ARMv8 64 bit based on Debian 11.3, ie, April 4 2022, does not.

Raspberry PI ARMv7 32 bit based on Debian 11.3, ie, April 4 2022 does not. Of course this one is the 32 bit VM and the 32 bit image but the identical image/vm combo as above.

Ubuntu 18.04 ARMv8 64 bit does it, also see below.
