sagetex does not convert number * symbol properly.

[kwangkim]

\documentclass{article}
\usepackage{sagetex}
\begin{document}
\begin{sagesilent}
from sympy import *
x=Symbol('x')
expr1= 4*x**2+1
expr2= x**2*4+1
\end{sagesilent}
$$\sagestr{latex(expr1)}$$
$$\sagestr{srepr(expr1)}$$
$$\sagestr{latex(expr2)}$$
$$\sagestr{srepr(expr2)}$$
\end{document}

Shows Which means sagetex does not convert '4*x**2+1' properly? I did it using cocalc.com

Could you give me an advice?

Something analogous happens with just sage instead of sagestr, where one gets (as expected) the latex() results above.

The really interesting part is that the strings returned by Sage seem to be identical:

sage: latex(expr1)
'4 x^{2} + 1'
sage: latex(expr2)
'4 x^{2} + 1'
sage: srepr(expr1)
"Add(Mul(Integer(4), Pow(Symbol('x'), Integer(2))), Integer(1))"
sage: srepr(expr2)
"Add(Mul(Integer(4), Pow(Symbol('x'), Integer(2))), Integer(1))"

but nonetheless somehow they are not coming out the same; maybe the internal representation, but I traversed both expression trees for these in Sage as well and can't find a difference. This would be worth investigating, but is relatively low priority since just avoiding Sympy (which after all isn't what SageTeX is designed for) would solve this particular issue.
