The 0.1s rescan only caught timers that change without a loss of control
event: a refreshed debuff fires UNIT_AURA, and a second kick on a locked
school fires SPELL_UPDATE_COOLDOWN, after ClassicAPI has read the lockout
from the packet. The alert listens to both while it shows. pfUI's
cooldown text prints the time left on the icon, so the alert's own
countdown and LOSS_OF_CONTROL_SECONDS go.
