gnuplot@5.0.5 on macOS 10.12.1 doesn't show a wxt terminal persistently

[twanvanderschoot (Twan van der Schoot)]

The summary says it all ;-)

When trying to use a wxt terminal in gnuplot script, running it with gnuplot opens a window, just long enough to show it did plot the graph, but then, about as quickly it opened, the window closes and disappears.

set terminal wxt persist

doesn't work, neither using persist on the command line

FYI: aqua and x11 terminals do work as to be expected with persist
