Amazing but it seems that there is an obvious bug in handling scroll events.

I am using Magic Track Pad in Safari so there is no visible drag-able scroll bar in the attribute panel. When I scroll the attribute panel, the scroll events just escaped the attribute panel and cause the glyph to scale. I must concede that the scaling is smooth and responsive, rendering this behavior quite funny but delightful.

Also, it would be more amazing if unicode were supported.
