Alignment on the baseline in a itemize environment with \dfrac{}{}

Alignment on the baseline in a itemize environment with \dfrac{}{}

[-- Attachment #1.1: Type: text/plain, Size: 397 bytes --]

The alignment of the second item on the baseline is not correct if I use the
command \dfrac{}{}.
How to solve this problem without using the command \framed ?
Best regards,
Fabrice

\starttext
\startitemize[columns,A,joinedup,three][stopper={)},style=bold]
\item  $f^{\prime}(x) = \dfrac{- 1}{(x + 1)^2}$
\item  $f^{\prime}(x) = 1$
\item  $f^{\prime}(x) = \dfrac{1}{x + 1}$
\stopitemize
\stoptext

1. You change your formulas.

\starttext
\startitemize[columns,A,joinedup,three][stopper={)},style=bold,grid=line]
\item  $f^{\prime}(x) = - 1 / (x + 1)^2$
\item  $f^{\prime}(x) = 1$
\item  $f^{\prime}(x) = 1 / (x + 1)$
\stopitemize
\stoptext


2. You enable grid snapping for the columns in the itemize environment with the grid key.

\starttext
\startitemize[columns,A,joinedup,three][stopper={)},style=bold,grid=line]
\item  $f^{\prime}(x) = \dfrac{- 1}{(x + 1)^2}$
\item  $f^{\prime}(x) = 1$
\item  $f^{\prime}(x) = \dfrac{1}{x + 1}$
\stopitemize
\stoptext


3. You increase the line height for the columns in the itemize environment.

\setupmixedcolumns[itemgroupcolumns][before={\setupinterlinespace[big]}]

\starttext
\startitemize[columns,A,joinedup,three][stopper={)},style=bold]
\item  $f^{\prime}(x) = \dfrac{- 1}{(x + 1)^2}$
\item  $f^{\prime}(x) = 1$
\item  $f^{\prime}(x) = \dfrac{1}{x + 1}$
\stopitemize
\stoptext

Hi Wolfgang,
Thank you for these three solutions. One thing I'm missing is the role 
of grid  I did not know.
