LaTeX causing recursion in dev build

[borela]

I have users reporting problems between the core LaTeX syntax and mine borela/naomi#117 , all the reports I got, either from friends or other users, were from people using the dev builds.

The issue is, I don't use the dev builds and everything works just fine so I can't test it.

From the looks of it, the biggest change in the LaTeX syntax was the introduction of the embed feature which should work similar to the with_prototype but pop all contexts, it could be a bug in the embed feature itself because the recursion does not happen in the build 3143.
