Mending Tridents and Bows Reseting

There's something really annoying with the trident and bow, if I have mending on them and they have lost durability, whenever I charge them up and EXP floats towards me and gets used by either the trident or bow then the charge up for them resets. This is very annoying as there was a creeper about to blow up my farm, so I took out my trident to kill it, but I just so happened to have killed a zombie with that same trident, losing some durability, it has mending and the EXP dropped by the zombie floated towards me and was applied to my mending trident, resetting its charge in the process, not allowing me to kill the creeper before it blew up my farm. I have experienced similar situations with a mending bow. Please fix this.
