`embark-act` with `prefix-help-command`

[jvillasante]

I'm using embark-act (bound to C-;) as a replacement for which-key as explained here: https://www.matem.unam.mx/~omar/apropos-emacs.html#the-case-against-which-key-a-polemic

The issue I'm having is that, after pressing <prefix> C-h to see all the candidates I have to press C-; twice to act on those candidates. The first time I press C-;, Emacs shows [No cycling possible; press C-; again to act.] and I have to press it a second time for it to work.

Embark is installed as follows:

(use-package embark
    :init (setq prefix-help-command #'embark-prefix-help-command))

Oh, I hadn't come across this bug before because I set embark-cycle-key to . (because I bind embark-act to C-., but don't want to use modifiers when I cycle). This bug only occurs with the default value of embark-cycle-key of nil (which means you cycle with the same key as with which you act). I'll think about how to fix this, it shouldn't be too hard.
