* Add copy button to markdown code blocks Done mostly in JS because I think it's better not to try getting buttons past the markup sanitizer. * add svg module tests * fix sanitizer regexp * remove outdated comment * vertically center button in issue comments as well * add comment to css * fix undefined on view file line copy * combine animation less files * Update modules/markup/markdown/markdown.go Co-authored-by: wxiaoguang <wxiaoguang@gmail.com> * add test for different sizes * add cloneNode and add tests for it * use deep clone * remove useless optional chaining * remove the svg node cache * unify clipboard copy string and i18n * remove unused var * remove unused localization * minor css tweaks to the button * comment tweak * remove useless attribute Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>forgejo
