Right, when hidden with CSS it’s still counted as a child because it still exists in the HTML.
CSS can mostly handle this now (with Firefox being the exception because it doesn’t yet support :has)… It’s probably worth adding a proper “hide 0 votes on topic list” option to the plugin to avoid the issue entirely… but for now this will work.
.vote-count-0 {
display: none; // hide 0 vote count
}
.discourse-tags:has(.vote-count-0) {
.discourse-tag:nth-last-child(2):after {
display: none; // hide the comma on the second to last tag
}
}
