`export PS1='value'` does not propagate to (Korn) subshells for root?

ksh

Please consider the following /root/.profile:

export PS1=value1
export x=value2

How come the login shell shows the expected prompt (and $x as value2), while the subshells keep showing $x as value2 but $PS1 as '#'? Just in case, I'm trying this under OpenBSD.

[Yeah, I know... What on earth am I doing with OpenBSD if I don't know this? Just toying... in an isolated, most definitely non-production VM =).]
