_ArrayDisplay() not honouring Opt("GUIDataSeparatorChar",...)

[partypooper@…]

#Include <Array.au3>
Opt("GUIDataSeparatorChar", " ")
$s_String = "ABCDE|FGHI JKL|MNO PQR|STUV WXYZ"
$a_Array = StringSplit($s_String, " ")
_ArrayDisplay($a_Array)

Should produce:
[0] = 4
[1] = ABCDE|FGHI
[2] = JKL|MNO
[3] = PQR|STUV
[4] = WXYZ

But instead produces:
[0] = 4
[1] = ABCDE
[2] = JKL
[3] = PQR
[4] = WXYZ

If the separator (" ") is physically specified in the _ArrayDisplay() command like the script below, it works as it should but then it's kinda pointless specifying Opt("GUIDataSeparatorChar", " ") in the script.

#Include <Array.au3>
Opt("GUIDataSeparatorChar", " ")
$s_String = "ABCDE|FGHI JKL|MNO PQR|STUV WXYZ"
$a_Array = StringSplit($s_String, " ")
_ArrayDisplay($a_Array,"",-1,0," ")

Working for me as fixed in the current beta.
It was not working under 3.3.0.0

Yes, my mistake JPM, it DOES work under current beta 3.3.1.1 but NOT for the current production 3.3.0.0.
