[l2h] Bug scalebox and input

[Klaus Frank]

If scalebox of the graphicx package is used in combination with input unexpected content apears on the final page:

html source code: view-source:data:text/html;charset=utf-8,%3Cdiv%20class%3D%22CENTER%22%3E%0A%3C!--%20MATH%0A%20%24%5Cscalebox%7B0.75%7D%7B%3C%7D%24%0A%20--%3E%0A%EF%B7%90%3Cimg%20style%3D%22%22%20src%3D%22img1.svg%22%20alt%3D%22%5Cscalebox%7B0.75%7D%7B%3C%7D%22%3E%26lt%3B9%26gt%3B%26gt%3B%EF%B7%AF%0A%20%20%20%20%20%20%20%20%20%20%20%20A%0A%20%20%20%20%20%20%20%20%0A%20%20%20%20%0A%3C%2Fdiv%3E

latex source code (the file test2 does not need to exist for this bug to occure):

```
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[hidelinks,pdfencoding=auto]{hyperref}
\usepackage[english]{babel}
\usepackage{graphicx}

\begin{document}
    \begin{center}
        \scalebox{0.75}{
            \input{test2}
        }
    \end{center}
\end{document}
```
