Thanks for isolating this very annoying bug.
I will take a look at it as soon as I will have time.
Here is an even shorter version:

--------------------------------------------------------------------
<TeXmacs|1.0.1.3>

<style|article>

<\body>
  <\expand|equation*>
    .
  </expand>

  It may be checked directly that these three matrices satisfy the
  commutation relations (<reference|sltwoarcr>).

  The bilinear form <with|mode|math|B(x,y)=<frac|1|2>> on is symmetric and
  invariant, as one easily checks.
