Every time I write an equation in the latex-ish equation environment and view it in the positron Visual editor, it's fine...until I click into it. When I do, it disappears from sight. It still renders properly in Preview and in a browser but the only way to "bring it back" to the Visual editor is by quitting and restarting. Then clicking in makes it disappear again.
This is in a mac version of positron. Something very similar happens in Rstudio, except that the raw latex is visible instead of the blank white space that positron shows.
This is an example of a working equation chunk..until it disappears...
$$ \begin{align} K_0 + U_0 &= K + U \nonumber \ \frac{1}{2}mv^2_0 + mgh_0 &= \frac{1}{2}mv^2 + mgh \label{KUconservation} \end{align} $$
anyone else seeing this?
