Bug description

The insiders stylesheet is different from the public stylesheet:

https://github.com/squidfunk/mkdocs-material-insiders/blob/master/src/assets/stylesheets/main/_typeset.scss#L293-L297

As opposed to:

https://github.com/squidfunk/mkdocs-material/blob/master/src/assets/stylesheets/main/_typeset.scss#L289-L312

It's missing the bottom-border attribute among other things making abbreviations indistinguishable on the site.
