19e09a7ce8a0aac0a7d534e1799e4d73b63a1bb5 by Abseil Team <absl-team@google.com>:

Update iter.position when moving up the tree in rebalance_after_delete.

This field isn't read after the first iteration in rebalance_after_delete, and I think it's not a correctness issue, but it is read in try_merge_or_rebalance and potentially affects rebalancing decisions so it can affect performance. There's also an extremely unlikely potential for undefined behavior due to signed integer overflow since this field is only ever incremented in try_merge_or_rebalance (and position is an int). Basically though, I just don't think it makes sense to have this invalid iterator floating around here.
