Fixes #5124

I personally think we should allow for blank issues even though we might prioritize them lower.

I can take it upon myself to triage all the blank issues if that's the sticking point.

* style: closes #3702

- Adds the two-column class with the expected style for two-column unordered lists, making sure to keep the two-column style at Features and Table of Contents
- Removes column style from ul element scope

* refactor: add two-column class to the toc

Use the class two-column instead of applying the style by using its id.

* refactor: move styles that are overwritten within other classes

Move margin-top and padding inside two-column as they are overwritten
within single-column.

* Include stack in browser uncaught error reporting

* Attempt at testing (failing due to uncaught exception)

* Revert "Attempt at testing (failing due to uncaught exception)"

This reverts commit 30c7ffb.
