-- When nvim starts up and restores a session including a toggle-term window,
-- we reach this condition, even if it will not be focused when startup
-- completes. For some reason, the mode change here would apply to the
-- eventually-focused window. So we need a further guard to prevent that.
-- Checking focused window doesn't work because the term window is briefly
-- focused as the plugin loads.
--
-- Thus: If the plugin has been loading for less than 2 seconds, assume it's
-- startup and don't change modes. Drawback is that we can't load a session
-- with focus on the terminal and have it start in insert mode.
--
-- FIXME: Find a better way to differentiate this situation.
