Bug de la fonction iconv_mime_decode

Pour info je viens d'envoyer le rapport de bug suivant :

Bad handling of RFC 2047 in case of folding white space

From manual page:

When there is a MIME encoded-word followed by a folding-white-space
(CR+LF+SPACE) followed by a simple word (not MIME encoded-word), the
function iconv_mime_decode doesn't add a space in between.

It works OK without the CR+LF.

My exact PHP version:

PHP 7.2.24-0ubuntu0.18.04.7 (cli) (built: Oct 7 2020 15:24:25) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
with Zend OPcache v7.2.24-0ubuntu0.18.04.7, Copyright (c) 1999-2018, by Zend

Test script:
printf("%s\n", iconv_mime_decode("=?UTF-8?Q?two?= words"));
printf("%s\n", iconv_mime_decode("=?UTF-8?Q?two?=\r\n words"));

Expected result:
two words
two words

Actual result:
two words
