The article Chữ khoa đẩu in the English Wikipedia shows "Page issues" on mobile web. It indeed has the {{Orphan}} template, but with the way in which it is used on this page, it's completely invisible on the desktop.
The irony is that the idea of the "Page issues" feature is to make such templates appear as small as possible on phones, but in this case it appears larger than on the desktop.
If it's physically invisible on the desktop, then it probably shouldn't be visible on the mobile view either.
(It would be even better if instead of manually maintained and language-specific templates this was handled by a real MediaWiki feature, but that is a huge project.)
