Why does BIOS assign memory to 16 byte BAR

From: Bharat Kumar Gogada

I'm observing that on x86 BIOS successfully assigns memory if an End point requests
BAR of size 16byte.

But as per Spec:
The minimum memory address range requested by a BAR is 128 bytes.

Why BIOS is successfully allocating region to 16 byte BAR requests?

Please let me know if my observation is wrong.
