Unnecessary reverse indent of \item in nested enumerate environment

[lutalli]

Description

The indentation of \item seems to work improperly in a nested enumerate environment (enumerate in another enumerate). When I enter an \item in a nested enumerate and type a space, the \item gets indented backwards unnecessarily.

Steps to reproduce

1. Begin with the following minimal TeX file:

\begin{document}

\begin{enumerate}
\end{enumerate}

\end{document}

2. Type \item in the enumerate environment, after that start another enumerate (where | stands for the cursor position):

\begin{document}

\begin{enumerate}
    \item \begin{enumerate}|
\end{enumerate}

\end{document}

3. Start a newline, type another \item (which belongs to the inner enumerate):

\begin{document}

\begin{enumerate}
    \item \begin{enumerate}
            \item|
\end{enumerate}

\end{document}

4. Type a space:

\begin{document}

\begin{enumerate}
    \item \begin{enumerate}
        \item |
\end{enumerate}

\end{document}

Expected behavior

The inner \item should stay in place after the space is typed, like this:

Actual behavior

The following recording shows the problematic actual behavior - \item gets falsely indented back:

Do you use a latexmkrc file?

No

Indentation is hard. So, before I agree this is a bug, let's first consider the example. Let's assume we use spaces and indent width of 2. Then the following should represent the example you provide:

\begin{enumerate}
  \item \begin{enumerate}
      \item hello
        world
      \item hello
        again
    \end{enumerate}
  \item hello
    moon
\end{enumerate}

I think my listing here also represents the correct indentation. And it seems that this does not work as expected now and so it may be a bug. But before I look closer, do you agree that this looks correctly indented to you?

Notice, just to be clear: I am not trying to align \begin and \end here. I am saying that \begin should add an indent, and similarly \item should add indent to succeeding lines before the next \item. Or, that's the idea, at least.

[lutalli]

Yes, I agree that the provided example represents the expected behaviour. There should be 3x indents before the inner \item, which consist of 1x given by the outer \begin, 1x by the outer \item, and 1x by the inner \begin.

I think this should be fixed now.

[lutalli]

I can confirm that the indentation works properly now. Thanks for fixing it!

Great, glad to hear it works!
