None of the above.  It's not a bug.  Your encoded string does not have a
trailing newline, and your $PS1 settings don't inject a starting
newline, so the behavior is expected.  If you want to guarantee a
trailing newline, then add one manually:

echo OHBjcWNLNGlQaVF5 | openssl base64 -d && echo

or modify your PS1 to start with a newline request.
