Steps to reproduce:
- Go to the doc subpage of any template page (e.g. https://en.wikipedia.org/w/index.php?title=Template:Infobox_airport/doc)
- Click "edit" link
- Click "Manage TemplateData" button
- In the list of "Template parameters", the alias pills on the right ("name, "nativename", etc) should have a complete border all the way around the text.
- The top and bottom borders are cut off:
This could be solved by adding a 1px padding to the containing div, which has class tdg-templateDataParamWidget-param-aliases.
