When flying or sprinting attempting to place down a block or spawn egg will place down more than one

I was on a super flat world and I got some spawn eggs. I was sprinting and holding down the right trigger, and literally hundreds of chickens spawned. Same story with flying forward. This is bad because if I was accidentally sprinting or flying and wanted to spawn a mob then I would accidentally spawn more than one. This is also the same story with blocks. and possibly other things. Please fix this!
