El texto encima de una línea en Tikz no funciona

Question

Tengo este código de mi publicación anterior enLa respuesta de Zarko., ahora el problema como puedes ver en elLa figura adjunta son las etiquetas. El código debería funcionar, también tiene que ver con mi versión de Latex o algo así. (Estoy generando la imagen a continuación usando el código)

\documentclass[12pt, margin=3mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{angles, arrows.meta,    % new
                quotes}                 % new
\definecolor{lava}{rgb}{0.81, 0.06, 0.13}
\definecolor{myblue}{rgb}{0.0, 0.30, 0.60}
%\usepackage{gensymb} % better is to use siunitx

\begin{document}
    \begin{tikzpicture}[
ang/.style = {draw, Straight Barb-Straight Barb, anchor=west,
              angle radius = 8mm, angle eccentricity=1},
arr/.style = {cap=round,-Straight Barb},
dot/.style = {circle, fill, minimum size=3pt,inner sep=0pt},
every edge quotes/.style = {auto, font=\footnotesize, sloped},
every label/.style       = {inner sep=1pt},
                        ]
% axis
\draw[arr]  (-2.7,0)--(3.6,0)   node[below] {$\Re$}; % x axis
\draw[arr]  (0,-2.7)--(0,3) node[left]  {$\Im$}; % y axis
% circle
\draw       (0,0) circle (2.5cm);
% defining radius points
\node (n1) [dot,label= 45:$V_m$] at (90:2.5) {};
\node (n2) [dot,label= 45:$P$]   at (45:2.5) {};
\node (n3) [dot,label=-45:$V_m$] at ( 0:2.5) {};
% vector
\coordinate (O) at (0,0);
\path[draw=lava, ultra thick, arr] 
    (O) to ["$V_m\mathrm{e}^{j\theta}$"]  (n2.center);
% projections
\path[draw=myblue, very thick, arr] 
    (O) to ["$V_m \cos(\phi)$" ']   (n2.center |- O); % projection on x axis
\path[draw=myblue, very thick, arr]
    (O) to ["$V_m \sin(\phi)$"]     (n2.center -| O); % projection on y axis
% angle
\pic [ang, "$\omega t+\phi$"] {angle = n3--O--n2};
    \end{tikzpicture}
\end{document}

El problema se resolvió agregando arriba y abajo a las etiquetas como el siguiente código

\documentclass[12pt, margin=3mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{angles, arrows.meta,   
                quotes}                
\definecolor{lava}{rgb}{0.81, 0.06, 0.13}
\definecolor{myblue}{rgb}{0.0, 0.30, 0.60}
\usepackage{steinmetz}
\usepackage{siunitx}     % new
\usepackage{amsmath,amsthm, amssymb, latexsym}
\renewcommand{\Re}{\operatorname{Re}}
\renewcommand{\Im}{\operatorname{Im}}

\begin{document}
    \begin{tikzpicture}[
ang/.style = {draw, Straight Barb-Straight Barb, anchor=west,
              angle radius = 8mm, angle eccentricity=1},
arr/.style = {cap=round,-Straight Barb},
dot/.style = {circle, fill, minimum size=3pt,inner sep=0pt},
every edge quotes/.style = {auto, font=\footnotesize, sloped},
every label/.style       = {inner sep=1pt},
                        ]
                        
 \def\Rad{3.25}                       
                        
% axis
\draw[arr]  (-\Rad-.3,0)--(\Rad+.5,0)   node[above] {$\Re$}; % x axis
\draw[arr]  (0,-\Rad-.3)--(0,\Rad+.5) node[left]  {$\Im$}; % y axis
% circle
\draw       (0,0) circle (\Rad cm);
% defining radius points
\node (n1) [dot,label= 45:$V_m$] at (90:\Rad) {};
\node (n2) [dot,label= 45:$P$]   at (45:\Rad) {};
\node (n3) [dot,label=-45:$V_m$] at (0:\Rad) {};
% vector
\coordinate (O) at (0,0);
\path[draw=lava, ultra thick, arr] 
    (O) to ["$V_m\mathrm{e}^{j\theta}$" above]  (n2.center);
% projections
\path[draw=myblue, very thick, arr] 
    (O) to ["$V_m \cos(\phi)$" below]   (n2.center |- O); % projection on x axis
\path[draw=myblue, very thick, arr]
    (O) to ["$V_m \sin(\phi)$" above ]     (n2.center -| O); % projection on y axis
% angle
\pic [ang, "$\footnotesize{\omega t+\phi}$"] {angle = n3--O--n2};
    \end{tikzpicture}
\end{document}
