What this PR does:

#5661 introduces a bug when backfilling the items. It is used in a for loop and goroutine closure, so we have to assign the variables again.

Added test cases to reproduce the issue. It could happen when we backfill more than 1 items and previous unit tests couldn't catch that.

Skipping changelog.
