[MC-53928] Dispenser Randomizer Count:0 does not work when the clock is too fast

When you update the blockdata of a dispenser to have a command block randomizer and you power the dispenser with a very fast clock (did not try with ultra fast) then command blocks inside will start to dissapear no matter how you set up the Count argument (capital, non capital, Count:0b,Count:0,....)

Command used:

/blockdata ~ ~ ~5 {Items:[{id:minecraft:command_block,tag:{BlockEntityTag:{Command:say 1},display:{Lore:["1"]}},Slot:0,Count:0},{id:minecraft:command_block,tag:{BlockEntityTag:{Command:say 2},display:{Lore:["2"]}},Slot:1,Count:0},{id:minecraft:command_block,tag:{BlockEntityTag:{Command:say 3},display:{Lore:["3"]}},Slot:2,Count:0},{id:minecraft:command_block,tag:{BlockEntityTag:{Command:say 4},display:{Lore:["4"]}},Slot:3,Count:0},{id:minecraft:command_block,tag:{BlockEntityTag:{Command:say 5},display:{Lore:["5"]}},Slot:4,Count:0},{id:minecraft:command_block,tag:{BlockEntityTag:{Command:say 6},display:{Lore:["6"]}},Slot:5,Count:0},{id:minecraft:command_block,tag:{BlockEntityTag:{Command:say 7},display:{Lore:["7"]}},Slot:6,Count:0},{id:minecraft:command_block,tag:{BlockEntityTag:{Command:say 8},display:{Lore:["8"]}},Slot:7,Count:0},{id:minecraft:command_block,tag:{BlockEntityTag:{Command:say 9},display:{Lore:["9"]}},Slot:8,Count:0}]}
