Why this change?

Now timerAlignmentInterval() takes an argument that is timer-specific so we can no longer call it here to determine if we should call didChangeTimerAlignmentInterval().

We need to call didChangeTimerAlignmentInterval() to notify all timers that their alignment may have changed. It is better to call this one too often rather than not enough as otherwise we may fail to update the interval of some timers.
If the document-level throttling state has changed, some timers in the Document (the ones that have reached the max nesting level) need to be updated so we need to call this function.
