The following code (copied from the math manual) doesn’t produce the intended

\starttext

\fenced[bracket]{\frac{1 + x}{1 - x}} = \fenced[bracket][size=0]{\frac{1 +
x}{1 - x}} = \fenced[bracket][size=1]{\frac{1 + x}{1 - x}} =
\fenced[bracket][size=2]{\frac{1 + x}{1 - x}} =
\fenced[bracket][size=3]{\frac{1 + x}{1 - x}} =
\fenced[bracket][size=4]{\frac{1 + x}{1 - x}}
\stopformula

What's the proper way of setting size in \fenced ?
There is a problem with the following command in math-fen.mkxl.
The internal parameter \p_factor is used twice for different keys.
