probably intended feature
I don't think this is intended. Most other things like torches only require to be placed on top of a solid face. The same should be true for mushrooms as well.

Can confirm in 1.16.5 and 21w08b.
Yes I would think this is a bug. It doesn't affect it. The stairs are upside down so it should be able to place.
Can confirm in 1.17.1.
Can confirm in 1.18.1.

Code Analysis:
(Decompiled with MCP)
Currently, the applicable blocks for placement are ones that are "isSolidRender" (Full cube blocks)
Possible Fix:
One fix for this, is to use "isFaceSturdy" instead, which only checks for a certain face of the block being applicable for placement (In this case, the top face).
This provides the following behavior:
Can confirm in 1.20.6 and 1.21 Release Candidate 1.
