Reduce failsafe time for animation events. This makes the lock-time more consistent.

We need to test |focusedPod| because |focusedPod| is set around line 3254 inside
"if (this.focusedPod_) {" below. If |this.focusedPod_| is not set, we would end
up with a JS error.

Also, for better readability, we should move decl "var focusedPod;" to the
beginning of the function to avoid confusions.
