[Feature Request] / [Bug] Ignore attack button being held down during item use with 'Apply the swing offset during item use' enabled

[motyI]

I'm not sure if this is a bug or a deliberate change compared to old versions, so depending on that this could either be a bug fix or a new setting for ensuring full parity with 1.7

I love the 'Apply the swing offset during item use' setting, but it has an annoying little issue - whenever using an item (holding down right click), if a person holds down left click, the attack animation plays on a loop, while I'm quite sure it should only play once, the moment left mouse button is pressed.

The current behavior is correct for whenever a player is doing all of the above AND looking at a block within their range - then the attack animation should indeed loop. But, when a player isn't looking at any block in their attack range, there should only be one attack.

I'm not sure if I explained it correctly, so here are two short videos showcasing the issue:
This is the mod's current behavior
This is the intended behavior

Let's assume in both clips I'm constantly holding down both mouse buttons. The attack animation should only be looped if the player is targeting a block, as seen in the clips

Are you sure you didn't enable the extras feature that does this?

I forgot to mention I did. Disabling it however completely removes the functionality to attack while using an item when not looking directly at a block

Sounds intended as you are supposed to swing then use the item for the visual animation, as that matches 1.7

Okay I felt the need to double check everything with vanilla 1.7, turns out I was indeed mistaken and this behavior is intended, apologies for that. My false beliefs originated from me always using non-vanilla clients when playing on lower versions, which have some additional settings, this one included. In this case may I suggest this behavior as an extra feature - the ability to attack while using an item? Purely visual of course, since for example attacking in the middle of eating would obviously constitute cheating

Small clarification: this would basically be the same setting as 'Allow usage swinging always', but it just wouldn't loop in air
