Texpresso Preview: `\reflectbox` and `\scalebox` render as 180-degree rotation, not horizontal flip

[Xiaobaituchb]

I've identified a rendering discrepancy in the Texpresso live preview for the \reflectbox and \scalebox{-1}[1]{...} commands.

While the final PDF compiled externally via latexmk displays the correct horizontally flipped (mirrored) text, the Texpresso live preview pane incorrectly renders the output as a 180-degree rotation.

Minimal Reproducible Example:

The following LaTeX code can be used to observe the issue:

\documentclass{article}
\usepackage{graphicx}
\usepackage{geometry} % Included to match example screenshot

\begin{document}

% Using \reflectbox
\reflectbox{b}

% Using \scalebox
\scalebox{-1}[1]{g}

\end{document}

Behavior Comparison:

• Correct Output (latexmk compiled PDF): The characters b and g are correctly mirrored horizontally, as expected.
• Incorrect Output (Texpresso Live Preview): The output characters are rotated by 180 degrees.

This issue suggests that the live preview renderer in Texpresso is misinterpreting the transformation for horizontal reflection.

Attached Screenshots:

Here is a side-by-side comparison. The left image shows the incorrect rendering in the Texpresso preview, and the right image shows the correct output in the final PDF generated by latexmk.
