Yes. I just tried it with `emacs -Q' with Emacs 26.3.  (I can't speak for master.)

The first time I tried the recipe I did not get the error; `C-h l' acted normally.

I followed the recipe again, in the same session, having done nothing in the meantime, I believe, and I got the error.  The second time I followed the recipe I used `C-b C-b C-b', but otherwise I did the same thing.

I think you just have to try a few times and you will see the error.  At least if you have the MS Windows Emacs 26.3 build (64-bit).  That's what I'm using.
