Description

Template {{tmp}} contains:
Lorem {{<includeonly>subst:</includeonly>#if:{{{1|}}}|foo [[{{{1}}}]]|bar}} ipsum

Calling {{subst:tmp|x}} gives (correct):
Lorem foo _x_ ipsum

(_x_ = x is hyperlink)

Calling {{subst:tmp}} gives (incorrect):
Lorem foo [[foo [[{{{1}}}]]]] ipsum
Should give:
Lorem bar ipsum

Two weird things:

replaced by the proper return string, literal "foo [[{{{1}}}]]", so we get
literal "foo [[foo [[{{{1}}}]]]]")
