LaTeX Render wrong - Sympy init_printing

Bug: Notebook Editor, trying to print using LaTeX

While using sympy in jupyter notebook in vscode, the output of the cell is not using the right “printer”… Very similar to issue #8742 but it is closed and I can’t post there.

Steps to cause the bug to occur

1. Open a jupyter notebook
2. write the following code:

from sympy import * 
init_printing(use_latex=True) # Tried the following as well: init_printing(use_latex="mathjax", latex_mode="equation")
var('x,y')
y = expand((x+y)**2)
y

3.run cell and see output

Actual behavior

Expected behavior

(ran the exact same code in jupyter lab)

Sorry but I don’t know. You could check by installing the August release to see if we did a better job then. We should be just leaving the text/latex as is. The renderer for that comes from nteract.

Yup, same behavior in the August release. Validated!
