Height and Width only increase image container

[tomhalley]

When increasing the size of a Sprite through the props, it only increases the height and width of a container, but doesn't scale up the size of the background image, meaning a 20px icon on a spritesheet when set to height or width 30, will just showing additional parts of surrounding sprites.

Similarly, changing the sprite image size down to 10px will just show a portion of the sprite, not a small version of the sprite
