# ConTeXt - weird vertical alignment in multicolumn enumeration

When I type math in a multicolumn enumeration, there is a gap in vertical alignment if I use fractions or matrices.

\startitemize[ columns, three]
\item $\frac{x^2-4}{\sqrt{x}-\sqrt{2}}$
\item $\sqrt{n} - \sqrt{n+1}$
\item $\frac{x^3-1}{x^2-1}$
\stopitemize

I can fix it with a tricky phantom

\startitemize[ columns, three]
\item $\frac{x^2-4}{\sqrt{x}-\sqrt{2}}$
\item $\sqrt{n} - \sqrt{n+1} \phantom{\frac{x^3-1}{x^2-1}}$
\item $\frac{x^3-1}{x^2-1}$
\stopitemize
\stoptext

Is there a cleaner way ?

Edit may be the same issue : is it possible to have a fixed interline space (in order to get an aspect similar to a table with fixed lineheight and without frame). For example this doesn't look good

\starttext
\startitemize[n, columns, packed]
\item $f(x) = 3\text{e}^{2x+1}-\ln(2x-3)$
\item $g(t) = \frac{t^2-3t+2}{t-1}$
\item $h(x) = \sin(\omega t + x)$
\item $i(t) = \sin(\omega t + x)$
\item $j(t) = \frac{\text{e}^{2t}-1}{\text{e}^{-2t}+1}$
\item $k(x) = \sqrt{1+x^2}$
\item $\ell(t) = \frac{1}{2+\ln(t)}$
\item $m(x) = \sqrt{1+\ln(x)}$
\item $n(x) = \sqrt{1+\ln(1+x^2)}$
\item $p(x) = \ln(1+\text{e}^x)$
\item $q(x) = \ln(x+\text{e}^{x^2})$

I'm not sure what, if anything, that has changed. You can try this (I changed your \text{e} into \mathrm{e}):
