Well, it is meant to be a feature, but it is going wrong here.

The idea is to capture "named theorems" such as:

\begin{thm}(Fermat--Wiles) 
...
...


Where the (....)  is the name of the theorem,
not part of the body of the theorem.

In your case, the ( is unclosed, and funny things happen.
I can program it to not count an unclosed ( as starting
a name, to prevent this.

The simplest way to override this "feature"
is to put a pair of empty braces:

 \begin{thm}
{}(....<math>...

Use:  {}( $\sin(x)$

> \end{thm}
> 

Thanks for the report.
