In T323141 we created a new layout container called .vector-column-start for the TOC and Main menu.
This however, was only implemented for compatibility with the Zebra CSS module.
Before merging the zebra module, we should make this new container compatible with the cached, non-zebra version of the HTML.
A/C
- When zebra is disabled (?vectorzebradesign=0) and the element .vector-column-start exists in the DOM, the ToC and sidebar still behave as expected
- When zebra is disabled (?vectorzebradesign=0) and the element .vector-column-start does not exist in the DOM, the ToC and sidebar still behave as expected
QA steps
not sure how what QA steps are for testing different cached versions of the HTML
