Dynamics not shown

In the following example, \p is shown only in bar 2.
Is this expected?

\version "2.20.0"
\include "oll-core/package.ily"
\loadPackage edition-engraver
\consistToContexts #edition-engraver Dynamics
\editionMod A 1 2/4 dd.Dynamics \p
\editionMod A 2 2/4 dd.Dynamics \p
\addEdition A
\score {
  <<
    \new Staff {
      a1
      <<
        { a1 }
        { s2 s2 }
      >>
    }
    \new Dynamics \with {
      \editionID dd
    } {
      s1*2
    }
  >>
}

Yes, this is expected, but intended to be improved.
The EE needs an event so that the hooks (start-translation-timestep, process-music et.al.) are called.
In Salzburg David came up with the idea of preprocessing the mods to inject. That way this problem could be solved.

Ok, thanks.
In fact I seemed to remember that was the case, but apparently I've been lucky enough and so far I didn't need to work around this.
