Emoji panel: handle window open event in post-1709 builds. Re #7273. In Windows 10 17000 and later (particularly after 17063 and later), when emoji panel first opens, window opened event is fired. This than allows NVDA to catch this and treat it as an item selected event, thereby allowing the first category to be announced.
