#2414 set tics front makes grid disappear

[Rafal]

I like gnuplot very much but in version 5.4.1 there is a strange bug. The way to reproduce:

set grid
plot sin(x) -> the function is plotted on the grid as expected

set tics front
plot sin(x) -> the function is plotted but the grid disappears
set grid front
plot sin(x) -> also no grid is plotted

This happens in Windows version 5.4.1 (binary package gp541-win64-mingw.7z) both in wxt and qt terminals.

Indeed. Strange. The same problem is present in the development version.
