I ran the test case and then chkdsk 5 times each on 1903, 2004 and 20H2 and it came back clean every time. It’s definitely possible I missed something but until it’s consistently reproducible then I’m on the fence. One complaint is I’d expect something at the level of MFT corruption to trigger a bugcheck (panic). Doesn’t seem safe behaviour to let the system carry on with a corrupt MFT.
