When using the LaTeX Workshop extension in Visual Studio Code, a white rectangle appears as a tooltip when hovering over LaTeX code (e.g., begin{equation} environments). Instead of showing a rendered preview of the equation, the tooltip displays a white box that does not provide any rendered output.

Steps to Reproduce:

1. Open a .tex file in VS Code with LaTeX Workshop installed.
2. Hover the mouse pointer over a LaTeX equation environment (e.g., begin{equation} … end{equation}).
3. Observe that a white rectangle appears instead of the rendered equation.

If you want to use the above equation, here it is:

begin{equation}
    label{eq:tangency-riskfree}
    begin{aligned}
        max_{boldsymbol{w}} quad & frac{boldsymbol{mu}_P - r_f}{sigma_P} \
        text{s.t.} quad & boldsymbol{w}^top boldsymbol{1} = 1\
        & 0 leq w_i, quad forall i
    end{aligned}
end{equation}

Expected Behavior: The tooltip should display the rendered version of the LaTeX equation or provide a preview of how the equation will appear in the compiled document.

Actual Behavior: The tooltip shows a white rectangle, not the rendered equation.

Troubleshooting Steps Taken:

• Verified LaTeX Workshop settings in VS Code.
• Ensured that the LaTeX document is properly built without errors.
• Checked for updates to both VS Code and the LaTeX Workshop extension.
• Restarted VS Code and tried various settings configurations.
• Confirmed that other LaTeX features, such as building and viewing the PDF, are working correctly.

Additional Information:

• The issue persists despite correctly configuring LaTeX Workshop and using supported file types (.tex).
• Other LaTeX functionalities (like PDF rendering) are working as expected, but the tooltip preview is not functioning.
