I usually do as follows: I put an absolute value around the expression and then erase manually the left bar. This sizes properly the remaining right bar. This:

<around*|\<nobracket\>|<frac|\<mathd\>|\<mathd\>x>|\|><rsub|x=0>

I’m not talking about the derivative one. I was talking about the one in the bullet point.

  <item>What about this?

  <\equation*>
    <around*|<left|\<nobracket\>|2>|<around*|(|asd|)>|<right|\||2>><rsub|x=0>
  </equation*>
</itemize>

what you use the method I suggested then you can resize manually the bracketing to be of larger size.
