Build menu hotkey is not working when loading the campaign game

[forGGe]

Describe the bug

Loading the saved campaign game in the offline mode results in the build menu hotkey not being functional.

bad.log

To Reproduce

• Run the client with ./run-offline
• Start any campaign map
• Save the game
• Load saved game
• Hit "B" on your engies to activate build menu

Expected behavior

The build menu is supposed to be activated, and build hotkeys are supposed to be overlayed on top of build icons

Additional context

It looks like missing HandleEvent is the problem in the gamemain.lua module:

construction.lua code in question:

if options.gui_draggable_queue ~= 0 then
    -- Add gameparent handleevent for if the drag ends outside the queue window
    local gameParent = import("/lua/ui/game/gamemain.lua").GetGameParent()
    local oldGameParentHandleEvent = gameParent.HandleEvent
    gameParent.HandleEvent = function(self, event)
        if event.Type == 'ButtonRelease' then
            import("/lua/ui/game/construction.lua").ButtonReleaseCallback()
        end
        oldGameParentHandleEvent(self, event)
    end
end

I can confirm that by disabling the "draggable queue" UI option in the option menu, it is possible to bring back the build mode hotkey functionality. Good enough as a workaround.

Among other things, "transmission log" feature is also missing if "draggable queue" is set.
