[BUG] DComboBox choices are unselectable when the DFrame is made modal.

[Khub]

local Window = vgui.Create( "DFrame" )
		Window:SetPos( 20, 20 )
		Window:SetSize( 600, 400 )
		Window:SetTitle( "Window" )
		Window:SetVisible( true )
		Window:SetDraggable( false )
		Window:ShowCloseButton( true )
		Window:SetBackgroundBlur( true )
		Window:SetDrawOnTop( true )

		LengthSelect = vgui.Create("DComboBox")
		LengthSelect:SetParent(Window)
		LengthSelect:SetPos(100, 115)
		LengthSelect:SetSize(200, 20)
		LengthSelect:AddChoice("b", "Option 1", true)
		LengthSelect:AddChoice("c", "Option 2")
		LengthSelect:AddChoice("z", "Option 3")

		
		

		Window:Center()
		Window:SetMouseInputEnabled(true)
		Window:MakePopup()

This code works. If I do that, then there's no problem.
However, when I add Window:DoModal() and then when I click the combo box, the options are drawn but they are not selectable. Does that only when it's part of modal'd frame.
