Introduced in bce9f4593a by @quicksketch, so asking for a review ;)

Fixed by PR backdrop/backdrop#2194

Thanks! I reset the $block_info array in your PR to be safe that we don't accidentally mix up items each time through the loop. Marking RTBC for merging after next test run finishes.

Merged backdrop/backdrop#2194 into 1.x and 1.10.x for 1.10.1.
