Items in columns are not top aligned the same

Question

If I'm using itemize inside a beamer column, the items are not the same way top-aligned as the items without a column. I want the symbols of both items in the images to be at the very same place.

\documentclass[t]{beamer}
\usepackage{blindtext}

\begin{document}

\begin{frame}{Heading 1}
  \begin{itemize}
    \item top aligned item nr. 1
  \end{itemize}
\end{frame}

\begin{frame}{Heading 2}
  \begin{columns}[t]
    \column[t]{.5\textwidth}
      \begin{itemize}
        \item item nr. 2, which is lower than item nr. 1
      \end{itemize}
    \column[t]{.5\textwidth}
      the other column
  \end{columns}
\end{frame}

\end{document}

Being a duplicate or not, you should try with the same kind of text in both columns: itemize+itemize or text+text, not itemize+text. — Ignasi, Apr 15 '16 at 14:11
Before paragraphs is only \parskip, but before itemize are \topsep + \parskip + \partopset. This cause observed difference in aligning of both kind of text on top of columns. A simple hack is to put negative vertical skip before itemize (which compensate this difference). — Zarko, Apr 15 '16 at 14:35
Maybe I didn't describe it right: I want the symbols of the items on slide 1 and slide 2 to be on the exact same position - the problem is not the other column on the right...
what negative skip would I have to add to compensate this spacing? — TyrenLament, Apr 15 '16 at 20:18

I don't understand why consecutive slides (which are not displayed at the same time) cannot be different, but ...

As it seems that columns environment introduces some vertical space before its contents, the first slide could be written inside a columns environment with one column. This way both spaces will be equivalent.

\documentclass[t]{beamer}
\usepackage{blindtext}

\begin{document}

\begin{frame}{Heading 1}
  \begin{columns}[t]
    \column[t]{\textwidth}
  \begin{itemize}
    \item top aligned item nr. 1
  \end{itemize}
  \end{columns}
\end{frame}

\begin{frame}{Heading 2}
  \begin{columns}[t]
    \column[t]{.5\textwidth}
      \begin{itemize}
        \item item nr. 2, which is lower than item nr. 1
      \end{itemize}
    \column[t]{.5\textwidth}
      the other column
  \end{columns}
\end{frame}

\end{document}

Items in columns are not top aligned the same
