ComboBox custom height not retained after window minimize

[Spiff59]

As shown in the example script below, if a user adjusts the item height of a ComboBox, once the window has been minimized and restored, the ComboBox will revert to it's default item height.

#include <GuiComboBox.au3>
#include <GuiConstants.au3>
Dim $hGUI

$GUI_Main = GuiCreate("", 245, 180, 200, 200)
GUISetFont(7.5, 400, 0)
$Combo1 = GUICtrlCreateCombo("", 20, 36, 200, 16, $CBS_DROPDOWNLIST)
GUICtrlSetData(-1, "1 WEEK|2 WEEKS|4 WEEKS|8 WEEKS|3 MONTHS", "1 WEEK")
_GUICtrlComboBox_SetItemHeight(-1, 12)

$button1 = GUICtrlCreateButton("click to minimize and restore", 20, 80, 200, 18)
$button2 = GUICtrlCreateButton("click to reset combo box height", 20, 120, 200, 18)
GUISetState()
Send("{TAB}")

While 1
    $msg = GUIGetMsg()
    If $msg = $button1 Then
        GUISetState(@SW_MINIMIZE)
        Sleep(100)
        GUISetState(@SW_RESTORE)
		Send("{TAB}{TAB}")
    EndIf
    If $msg = $button2 Then
        _GUICtrlComboBox_SetItemHeight($Combo1, 12)
    EndIf
    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
Wend
Exit

If you use _GUICtrlComboBox_SetItemHeight() function you must create the control with _GUICtrlComboBox_Create().
The resizing stuff of GUICtrlCreateCombo() is relevant only with GUICtrl...() functions.
Don't mix GUI... Builtins with UDF.
Perhaps one day the situation will change when Valik commit an update of the Builtins functions

In that case, _GUICtrlComboBox_SetItemHeight() has no useful purpose at all, as I can find no way to adjust the font size of a ComboBox created with _GUICtrlComboBox_Create().

If one wishes to have a ComboBox with less height than the default, you either:
A) If created with GUICtrlCreateCombo(), suffer the box reverting to it's default size after a minimize/restore,
-or-
B) If using _GUICtrlComboBox_Create(), you are unable to set the font size small enough to fit in the "skinny" ComboBox.

It is certainly possible with _WinAPI...() functions to do the same as AutoIt do for builtin function.
Using UDF in lower detail need a lot of knowledge.
