I've attached a patch for this. It shouldn't be controversial because it only reduces the possibility for surprises, but doesn't change any behavior.

Thanks. Does the patch below fix the issue, without introducing any
adverse side effects?

It does introduce the adverse side effect that now the first blink takes one second (the sum of cursor-blink-delay and cursor-blink-interval). I've attached another patch with the change I have in mind.
