Stickybomb world viewmodel is visible while in a portal seam

[hexaflexahexagon]

Describe the bug While standing in the seam between two portals, a second model of the stickybomb launcher is visible on the bottom of the screen. Doesn't seem to happen with any other weapons that I can find. Still happens with r_drawviewmodels 0

Does this still happen with cl_modelfastpath also on?

[hexaflexahexagon]

cl_modelfastpath 1 is default and probably what was on when this was reported, this seems to still happen regardless of the value.

Probably related to the sniper and other weapon models that dont use hands having the same bug, everywhere (not just in portals).

Sticky and rocket launchers were updated to use the same model for the viewmodel as the worldmodel, so it's likely to do with that somehow.
