Block particles displayed in corner of area when using destroy option in fill command

Steps to reproduce:
1. place blocks in an area greater than 1x1
2. execute the /fill command like so: /fill x1 y1 z1 x2 y2 z2 minecraft:air 0 destroy

Expected results:
1. all non-air blocks are replaced with air
2. block break particles show for each non-air block broken at its coordinates before it was broken
3. a message in chat appears detailing the number of blocks replaced

Actual results:
1. all non-air blocks are replaced with air (this part works)
2. block break particles show at the maximum x-y-z value in the area specified in the /fill command
3. a message in chat appears saying "no blocks filled"

Notes:
I have attached the same command run in 17w17b and 17w18a with the different results, before and after the command is run
