It's a bug to the fairly recently added facility to hide the header. The
table was never intended to have its header hidden, and I thought we'd come
up with a viable solution to do it (people were requesting it) but
apparently that solution doesn't work. Please create a bug report for this,
and include as much detail as you can. (A playground example that causes the
problem, along with instructions for reproducing the problem, would be very
useful.)
