+ pants. We do this two ways: a racy way and a non-racy way.
+ We kick it after a second which is ideal if we win the race,
+ because the user gets to hear what widget they are in, and
+ the first character will be masked. Otherwise, if we lose
+ that race, the first time the user types (see
+ DashEntry.key_press_event), we will kick orca again. While
+ this is not racy with orca startup, it is racy with whether
+ orca will read the first character or not out loud. Hence
+ why we do both. Ideally this would be fixed in orca itself.
