Orbiting Fire glitches into Pyro's torso and disappears if unusual height selection is checked

[cringeproducer]

Description

When using an unusual with the effect Orbiting Fire on Pyro, the effect is glitched and when using height selection, the effect sometimes shows up orbiting around the Pyro's head but sometimes when taunting, the effect disappears.

Also, when using the Orbiting Fire effect without the height selection box checked, the effect is always present (even while taunting) but is moving around the Pyro's torso instead of the Pyro's head.
