@colemanw can you check this - seems surprising we would need sortable as an id but ..... (I think it's datatables)

[magnolia61]

I based this correction on other places in the code where it is also used (with id instead of class).
And a final argument to merge this one. It works and saves us a lot of time editing the templates ;-)

What a compelling case :-) OK
