User:Simetrical/texhtml bug

Each of the following list items has <math> wrapped around its contents.

• $x$
• $xy$
• $xy$
• $x-y$
• $x/y$
• $x*y$
• $x\times y$

Expected result: Any input to <math> gets italicized and put in a serif font, due to wrapping in <span class="texhtml">.

Actual result: Any input that uses no LaTeX commands and only uses ASCII characters is outputted with whitespace stripped but otherwise as-is, not wrapped in any HTML tag.
