Incorrect rendering of `\sum` etc. with `\nolimits`

Issue Summary

Sums, products, unions etc. with \nolimits result in incorrect rendering.

Thanks for the report. I have made a PR to resolve the issue. One solution in the meantime is to move the \nolimits to being right after the operator:

1 \sum\nolimits_a
