So, if you have tried those exact steps and are not seeing it, then perhaps  it is an issue similar to a previous one a few months ago.  A few months ago, you discovered that I was using a certain set of tools to build Emacs, which was different than the ones you are using, and that was the reason I was seeing a bug with the help menu.  I mention this because I'm still using the same tools to build Emacs.  I don't remember the name exactly, but it was something like "clang".

I build with clang.

And hiding will not work again for other applications unless OSX is restarted, or unless you clock on Show the Dock and then Hide the Dock again to restore functionality.

I still can't reproduce it.  Dock hides as it should in all applications after following your steps.
