[ncurses] Nano editor sets wrong fg/bg colors

[ivrntsv]

Description / Steps to reproduce the issue

1. Set mintty theme to kohlrausch. This way it's more evident as kohlrausch is black on white theme. Though, with other themes (but not all) it's the same.
2. Run nano.

For the full story please read the thread following the links: start, continuation.

What helped is downgrading ncurses package from 6.5.20240831 to 6.5 version.

Expected behavior

Nano respects theme colors.

Actual behavior

Nano uses white foreground and black background colors.

I can confirm:

• the issue
• downgrading ncurses solves it
• the issue doesn't exist in cygwin which has a slightly older ncurses
