[Portrait Helper] Weapon animation not in sync

[Haselnussbomber]

Summary
Scrolling the animation timestamp forward does not advance the weapon animation of emotes like Battle Stance or Victory.

Workaround
Scroll backwards. 🤷‍♂️

Reason
The animation system is still not fully understood/reverse engineered. But because forward and backward scrolling use different techniques in the plugin, the animation will be reloaded when scrolling backwards and that'll update the weapon positions too.
