Animated Sprite Current Time Infinity on Tab Change

Hey guys, I found an issue with Animated Sprites / Movie Clip. When I change tabs with an animation running, the whole game breaks.

When you have a running animation, the current frame is calculated with this:

AnimatesSprite.js 372: var currentFrame = Math.floor(this._currentTime) % this._textures.length;

However, when you change tab, this._currentTime is being set to Infinity, and so this._currentFrame is being set to NaN. This in turn causes this._textures[this._currentFrame] to return undefined and then the renderer crashes because an invalid texture has been set on the sprite.

I did a quick isFinite stop this from breaking the renderer.

` get: function get() {

    if(!isFinite(this._currentTime)) {
        this._currentTime = 0;
    }

    var currentFrame = Math.floor(this._currentTime) % this._textures.length;       

    if (currentFrame < 0) {
        currentFrame += this._textures.length;
    }

    return currentFrame;

} `

Hope this might help someone else too!
