stats for stat.useItem.minecraft.spawn_egg doesn't add value to scoreboard when in gamemode 2

I have a strange issue regarding scoreboards and stats
Only in gamemode 2 the value of stat.useItem.minecraft.spawn_egg
doesn't count up when using a spawn_egg.
In every version before it worked fine.

To reproduce the problem do the following:

Add a scoreboard:

/scoreboard objectives add egg stat.useItem.minecraft.spawn_egg

/scoreboard objectives setdisplay sidebar egg

After this you can change gamemodes and see that it only counts up when in gamemode 0 or 1.

Also tested if it has something to do with /gamerule doMobSpawning. Both (true/false) states doesn't change anything. I tested it only with a spawnegg (btw. it has metadata 0 but it doesnt affect anything when using another spawnegg).
