Or'ing curses.A_COLOR in the `attr` argument of curses.window.chgat ends of with the line not showing.

Actual Problem:
The text is invisible/hidden/not shown.
Using only the attribute curses.A_BLINK is fine.

Expected:
The color of the line is changed +the text starts blinking.


I have attached a small python reproducer and a small c source that shows the correct behavior.
The c example should be compiled as `gcc chgat.c -lncurses -o chgat`.

This is using ncurses 6.1

The c code is from https://tldp.org/HOWTO/NCURSES-Programming-HOWTO/attrib.html,
and the python script is a translation of it.

Equivalent c script of chgat.py

Compile with:
gcc chgat.c -lncurses -o chgat
