import sympy.physics.quantum as q
import sympy
sympy.init_printing(use_latex="mathjax")
ket = q.Ket("x")
q.Dagger(ket) * ket
Which has this output $\displaystyle \left\langle x \right. {\left|x\right\rangle }$.
This is how it is displayed in VS Code:
But it should be displayed correctly as: $\displaystyle \left\langle x \right. {\left|x\right\rangle }$.
This is a problem due to the MathJax implementation of VS Code inside the notebook I guess.

What happened?
This issue comes from https://github.com/sympy/sympy/issues/25979.
Which has this output
$\displaystyle \left\langle x \right. {\left|x\right\rangle }$.This is how it is displayed in VS Code:
But it should be displayed correctly as: $\displaystyle \left\langle x \right. {\left|x\right\rangle }$. This is a problem due to the MathJax implementation of VS Code inside the notebook I guess.
