We've shipped some 4.6.z without this fix, so not a blocker.
I tried 5 times installation with 4.6.0-0.nightly-2020-11-15-104235 on baremetal and all passed.
Could you please verify it using assistant-installer on your side?
I'm moving it to verified based on comment#4.
Which 4.6.z includes this fix?
the Fixed In Version field is currently blank.
It is in 4.6.5, but that did not get released :
