Not quite trivial, especially when it uses safesubst:

• http://web.archive.org/web/20110800000000/http://code.pediapress.com/wiki/ticket/940
  • Handle "safesubst:"
  • new – ralf – urgent – major – 8 months
  • Can't tell, the template content is output within a <table>, currently stripped

Description ¶

In Template:Collapse top, some instances of "safesubst:" is encountered, and breaks rendering.

See

The first instance is transcluded normally (fails to render adequately). The second is substed, and renders fine.
