https://en.wikipedia.org/wiki/User:DePiep/VEdemo?veaction=edit The use of tl is not rendered, but tlx is.
This template isnt used in any pages in namespace 0, and is not likely to appear often in userspace drafts either. However whatever is triggering this bug may be triggering other templates to be silently dropped. fwiw, the page has an empty span where the {{tl}} is supposed to appear, with lots of attributes set.
*** Bug 52147 has been marked as a duplicate of this bug. ***
Also doesn't render in Parsoid it seems: http://parsoid.wmflabs.org/en/User:DePiep/VEdemo I presume this is caused by the {{ }} characters in this template that are used 'unescaped'/not nowikied. It seems that PHP parser is able to detect that {{[[ ]]}} is not a valid template syntax, but that parsoid tried to transclude regardless and resolves to 'null' content.
Doesn't render in Parsoid === Parsoid bug :)
Since this bug in the Parsoid component in bugzilla, the 'Parsoid:' prefix is redundant. I have an old WIP patch in a working branch .. will dust it off this coming week.
