 You might be right here. However, this is not the whole story. I see in
 fact the second execution in my logs although only after we called
 OpenBrowserWindow(). My guess is that the second execution happens somehow
 in this new window context which is not properly initialized yet. Anyway,
 I don't have the time to look deeper at it right now to understand what is
 exactly going on under the hood.
