Coming from [mathieu stumpf guntz's praise for the new print styles on Wikitech](https://lists.wikimedia.org/pipermail/wikitech-l/2017-October/088969.html) and looking at article mentioned by him the TOC layout is incorrect with numbers higher than 10 when compared with layouts at https://app.zeplin.io/project/58b5f95e7b103f89913c25de/screen/5971579e3ec2ea33c89bf2c1
{F10528195 width=50%}
This is demonstrated when printing https://fr.wikiversity.org/wiki/Recherche:Lex%C3%A8mes_fran%C3%A7ais_relatifs_aux_structures
Expected: Left edge of 16.1 should align with left edge of 'L' in "Lexèmes"
= Developer notes
As @phuedx points out, this is caused by .tocnumber using margin-right: 30px to set its width. Unfortunately, this means that the width of the element (the list item number container) varies with the width of its content.
