Switching hot bar glitch

When I right click a snowball/fishing rod/eggs, and switch back to my sword quickly, it will sometimes not throw the snowballs/fishing rod/eggs or it might not switch to the sword and instead it will go back to the previous slot and it is really annoying. Because, I deal knock back with the snowball/fishing rod/eggs, then try to switch back to my sword and I think I'm holding my sword but I'm not and its the snowball/fishing rod/eggs that I'm holding, and it usually causes me to die.

 

Please fix this I would be really happy if you do
