Raw TeX commands are displayed.
More or less the same as in bug 33399. If JavaScript features in LivePreview don't work for core features one can't expect it to work for extensions. A hook system as suggested in bug 23580 would be the best way to fix this bug. See also bug 35478.

Re-opening as this needs two things: * Be able to get modules loaded that extensions add to the page (bug 24134) * Be able to run code for "article loaded" when the article html is loaded. Usually this is document-ready which is how we do it now, but in case of preview we have multiple "article loaded" points within the lifecycle of a single page. This will be made possible by 30713.
MathJax module now has a $().renderTex command that can be run to render domelements that contain tex commands. A preview hook can use this to postprocess the preview output.
(For the record, there is now a fix in progress for bug 30713 which is a dependency here.)
Both Ajaxpreview and wikEd now use the renderTex() command to render MathJax in their ajax based preview modes: Example: https://en.wikipedia.org/w/index.php?title=User%3AJs%2Fpreview2.js&diff=558032369&oldid=520879456 Soon to be improved by making use of https://gerrit.wikimedia.org/r/56762
A specific problem is that after a session in VisualEditor a full refresh is not done and MathJax is not rerun, so the raw latex code is displayed. Apparently according to bug 51565 gadgets should listen to "wikipage.content". I have heard rumours that the fix to bug 48560 will fix this problem.

Patch was merged a while ago - is there more work left to do here (if yes: please reset the bug report status to NEW or ASSIGNED), or can you close this ticket as RESOLVED FIXED?
I just tested and it still doesn't seem to work (PNG images are shown).
For LivePreview, it depends on bug 24134 which isn't fixed yet, because I still need to finish https://gerrit.wikimedia.org/r/#/c/131346/. The patch that was merged was just one of the prerequisites. VE is a separate issue.
