Part of grid is sometimes missing

[tgkolda]

I have noticed that the upper/right parts of the grid are sometimes missing in pgfplots. I include an example. This fails with my local installation uisng MikTeX as well as on Overleaf. Observe that the lower & lefts parts of the grid are fine. This does not always happen. For instance, using xtick distance=2, minor x tick num=1, the left grid is fine. This is certainly a minor problem, but perhaps worthwhile to fix in some future edition.

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}

\begin{document}

\begin{tikzpicture}
    \begin{axis}[
        scale only axis, height=10cm, width=8cm,
        axis lines=middle,
        grid=both,
        xmin=-8, xmax=8,
        xtick distance=4, minor x tick num=3,
        ymin=-12, ymax=12, 
        ytick distance=4, minor y tick num=3,
        enlargelimits={abs=1.9},
        ]
    \end{axis}
\end{tikzpicture}

\end{document}

The result is:
