Thread:Project:Support desk/Pipes in templates that break tables

Compare http://is.wikipedia.org/wiki/Notandi:Bjarki_S and https://no.wikipedia.org/wiki/Bruker:Bjarki_S

Does anyone know why | in the template breaks the table syntax on is.wiki but not no.wiki? I have no idea whether this is because of a different extension setups or different javascript configurations or something else.
