What I don't get about this is that io is already initialized to outstream(d.repl), so this should not be necessary. Is something else adding a :displaysize key here that's overriding it?

I think the actual problem is in arrayshow.jl:

            sx = sprint(show, "text/plain", x, context=io, sizehint=0)

in print_matrix_row. It tries to inherit the context but the displaysize is not included.

Okay, will try that then.
