Recipe Book Lag When Clicking on a Recipe Too Fast

This is not so much a bug as it is a hazard to multiplayer servers. 

 

When you have items in your inventory which is able to craft an item shown in the recipe book, you can click the recipe to automatically put the items into the crafting grid. If you do this too fast, like with an auto clicker, I presume the server is unable to keep up with knowing where the items are supposed to go thus causes immense amounts of lag. I tested this on a multiplayer server and in single player and was able to bring the tps down to 1 or 2.

To re-create this you must:
-Have a fast auto clicker

-Have items able to craft something (I used 9 stacks of gold ingots to create blocks).

-Then you must use the auto clicker to spam the crafting recipe.

The lag will stop once all the items are in the right place but to increase the amount of time the lag will be, you can move your cursor over other recipes available forever.

Something which may be able to prevent this is having a limit to how fast you can click the recipe, maybe a max of 20 per second maybe even 10 times per second.

(My auto clicker was running at around 220 clicks per second but this could probably work with lower clicks per second values)
