Bug fix for the Blizzard calendar: prevents unexpected window closure while editing events
There is an annoying bug in the event window of the Blizzard in-game calendar that causes the event description or title edit box to lose keyboard focus at random times (specifically, upon receiving a GUILD_ROSTER_UPDATE event from the server). If the user happens to be typing an event description when this happens, the loss of keyboard focus enables keybinds, which often results in closure of the calendar window, discarding unsaved changes.
This tiny fix-it addon corrects that bug.
Legion Update: The calendar bug was fixed in WoW 7.0, so this fix is no longer necessary.
