Properly set displaystyle and scriptlevel, and make sure the contents is enclosed in a single element. Resolves both parts of issue #1152, but at the cost of possibly redundent mstyle elements. These could be filtered out in the combineRelations() post-filter, when we can check if the displaystyle and script levels need setting.
