The problem about the previous version of mw and visualeditor was that when a new page is created and math is inserted the visualeditor didn't visualize the formula. If instead, a page with some math content was edited, then it worked correctly.
With the new version the problem may have been solved.
TODO: try, both on local instance and on .vodka, to:
- create a new page and immediately insert an inline formula
- create a new page and immediately insert a block formula
- edit an existing page without math and try to insert both an inline and a block formula
- edit an existing page with math and try to to insert both an inline and a block formula
