Scenario 1 (the bug): Player Inventory / Book A / Book B, Book B pinned on quickbar. I cannot open Book B (located in my inventory) from the quickbar. For comparison:
Scenario 2: Player Inventory / Book A / Book B, Book A on quickbar. I can open Book A and anything inside it, including Book B.
Scenario 3: My blueprints or Game blueprints / Book A / Book B, Book B on quickbar. I can open Book B from quickbar.
I reproduced all three scenarios without mods. Here's a save file in case it's just me:

I wonder if this is another symptom of the fix to 102095, which in turn caused other issues like the one in 102322?

Most likely that is the issue. The root problem is books were written ignoring the core mechanics of item-with-inventory.. unfortunately. So once that was fixed generically it broke the blueprint book behavior.
