Icons in message box

It seems like the MsgBox function ignores icons.

*Sub Test*

* Dim iReply As Integer iReply=MsgBox("Do you feel like pressing the
Yes button?", _ MB_YESNO OR MB_ICONQUESTION OR
MB_DEFBUTTON2, _ "Your choice")*
*End Sub*

I expect a message button with a Yes and a No button. the latter being
default. I also expect the message box to display a big question mark.
The constants I'm using are described in the file
”/usr/lib/libreoffice/help/en-US/text/sbasic/shared/03010102.html” (at
least on Manjaro Linux), and I will include them here:

MB_OK

0

Display OK button only.

MB_OKCANCEL

1

Display OK and Cancel buttons.

MB_ABORTRETRYCANCEL

2

Display Abort, Retry, and Ignore buttons.

MB_YESNOCANCEL

3

Display Yes, No, and Cancel buttons.

MB_YESNO

4

Display Yes and No buttons.

MB_RETRYCANCEL

5

Display Retry and Cancel buttons.

MB_ICONSTOP

16

Add the Stop icon to the dialog.

MB_ICONQUESTION

32

Add the Question icon to the dialog.

MB_ICONEXCLAMATION

48

Add the Exclamation Point icon to the dialog.

MB_ICONINFORMATION

64

Add the Information icon to the dialog.

128

First button in the dialog as default button.

MB_DEFBUTTON2

256

Second button in the dialog as default button.

MB_DEFBUTTON3

512

Third button in the dialog as default button.

Seems like all the MB_ICONxxx options are ignored.
I just want to find out if this is a bug or not. Maybe the problem is my
theme or something, so I just wonder if this works for anybody else.
Thanks.

Kind regards

I do see the question mark.

I'm not using a theme.

So do I. If I change the MB_ICONQUESTION constant for the MB_ICONSTOP, I see the Stop icon as well.
