Slight FOV decrease after mid air charged punch into mantle

[liar]

If you perform a mid air charged punch into a mantle, your FOV will decrease slightly for ~5 seconds before going back to normal.

For this to happen you need to:
Be in the air
Perform a charged punch (It has to be a charged punch)
Mantle while still being in punch animation (it can not be after the animation has finished)

As far as I know it does not matter how you get in the air. This will happen while falling into punch then mantle, wall jumping into punch then mantle or just jumping into punch then mantle.

I can replicate it at will and it's consistent
If you punch while your FOV is still decreased it will go back to normal
I've attached an example video:

bumping this, never had this interaction until wall jumping came out
still reduces ur fov

included example, happens on any backwards wall jump -> strong melee -> mantle

fov resets to normal at 8-9 second mark

After coming back to this and testing some more, I found out that anything that cancels a heavy melee while in the air will decrease your fov.
Just like in my original post you still have to cancel the melee while the animation is happening.
Certain heroes can do this with abilities, but of course every can hero can have this happen if you recreate the mantle from my original post.

I tested all the different hero abilities and all the active items and I list them all below

Items:
Fleetfoot

Heroes:
Abrams with his 1
Dynamo with his 4
Infernus with his 4
Ivy with her 3
Kelvin with his 2
Mo & Krill with their 1
Paradox with her 3


Some examples:

Fleetfoot - Heavy melee while in the air, then using the active item "Fleetfoot", If you time a slide afterwards, your fov will zoom in for a short while before zooming it out and then finally returning to normal.

Abrams - Heavy melee while in the air as Abrams, then using "Siphon Life" (1)

Ivy - Heavy melee while in the air as Ivy, then using "Stone Form" (3)
