Sorry this has taken a while, but I'm hopeful this should now be
fixed in the current snapshot for 64-bit Windows.

I found a relevant discussion on the gnuplot developers' list with a
patch to fix the font size issue. The patch postdates the gnuplot
5.4.1 release so it's not surprising that updating to 5.4.1 didn't
help.
