Research direction
Reproduce the four parent-width examples in the issue and start at StackBlur.js:83, where the canvas image-data error occurs. Trace how the Blur component determines its canvas dimensions relative to each parent. Done means the examples no longer produce an IndexSizeError and the canvas matches the parent width and height.
