I don't think there's a specific antecedent for "it" in that expression. Its use is similar to the use of "it's" in the following:
It's raining hard right now.
It's really dark outside, isn't it?
It's 99 degrees and humid outside.
The impersonal "it."
The dog has almost gone blind. He said, 'It's strange. These days you look blurry.' (You refers to the dog's master.)
------------------------------
What does 'it' refer to in 'It's strange'? Does it refer to 'situation'?
