works only in newer versions like 1.14,4 and above

if place button is binded with a lot of diffrent things for example (spacebar) if being held allows you to use fishing rod, place blocks, or open doors extremely fast

Expected result: if fishing rod is held using this method it should cast the rod and retrieve it in short interval

Actual result: if fishing rod is held using this method will make the process of casting and retriving at least 20 times quicker than normal

how to reproduce: in minecraft go to controls settings and bind (place block) as spacebar instead of ussual right click then grab fishing rod and hold space 

this bug can be exploited on many minigames including fast clicking right button for example eating cake on minigame the pit.
