Steps to replicate the issue (include links if applicable):

• Case 1:
  • Open mw:Template:User link/doc, which contains the wikitext {{tsh|u}} (invoking Template:Template shortcut to display a page status indicator).
  • If you use the legacy parser, the page status indicator correctly displays "shortcut: {{u}}". If you use Parsoid, the page status indicator is not displayed.
• Case 2:
  • Open mw:Template:User link, which transcludes mw:Template:User link/doc.
  • If you use the legacy parser, the page status indicator correctly displays "shortcut: {{u}}". If you use Parsoid, the page status indicator incorrectly displays "shortcut: {{tsh}}" (the shortcut to Template:Template shortcut).
