Why the arc does not fit over the circle if we use -latex
arrow tip? Maybe some bug or some bad math computations?
MWE
\documentclass[11pt,margin=2pt]{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta}
\begin{document}
\begin{tikzpicture}
\draw (0:1cm) arc (0: 180:1cm) arc (180:0:1cm and 2cm);
\draw (0:1cm) arc (0:-180:1cm);
\draw[->] (0:1cm) arc (0: 80:1cm);
\draw[-latex] (0:1cm) arc (0:- 80:1cm);
\end{tikzpicture}
\end{document}

This is a solution using marking. It does not draw any additional curve. Thus there is no chance to have any curve overlap.
