Bug> Tinted sprite is not cropped propely

When using original textures that are HTMLImageElement, cropping image works fine, but it doesn’t work when cropping tinted images created by cc.generateTintImage function.
And I found a spot that doesn’t use ’this.*rect.origin’ in CCSprite::draw
@
context.drawImage,
this.*rect.size.width, this.*rect.size.height);

As you can see, the parameters for origin positions set to zero. It seems that they should be fixed like next.

@ context.drawImage,
this.*rect.size.width, this._rect.size.height);
