Setting visualisation variant replays animations

[Silier]

I am playing with gate garrisoning and I found that after this call in GarisonHolder

 cmpVisual.SetVariant("garrison", this.entities.length ? "garrisoned" : "ungarrisoned");

are again replayed gate_opening or gate_closing animations without calling functions in Gate.js, so it is done by visualisation component.

Animations running once should be unselected by visualisation component itself.

If that's a bug it needs a patch
