As of today, the section edit links seem to have reverted to the old style ([edit]). They don't expand and they open the source editor, even though VE is enabled (the 'Edit' and 'Edit source' tabs are there at the top. See screenshot.
Observed on en.wp (by me and User:KTC) and fr.wp (by me). KTC used firefox and chrome, and I used firefox 21.
