imagefttext() ignores clipping rect for palette images

[cmb69]

Description

The following code:

<?php
$im = imagecreate(64, 32);
$bg = imagecolorallocate($im, 0, 0, 0);
$fg = imagecolorallocate($im, 255, 255, 255);
imagefilledrectangle($im, 0, 0, 31, 31, $bg);
imagesetclip($im, 32, 0, 63, 31);
var_dump(imagettftext($im, 16, 0, 7, 23, $fg, "DejaVuSans", "hello"));
imagepng($im);

Resulted in this output with bundled libgd:

But I expected this output instead (like external libgd):
