Maybe update the comment to say that the main resource was block, and rename the
method to NotifyMainResourceBlocked.

Its depending on be called prior to cache selection time to work properly. If
this gets called after cache selection time, its a noop. All resource loads
except the main resource load happen after cache selection.

So "main" is significant.
