    <thetext>SUMMARY:
We are creating an element, filling it with a color, and using -webkit-mask-box-image to mask the element into a shape.

BUG:
Once rotated or transformed, pixel &quot;fringe&quot; shows up on the outside of the element, like a very thin border.
This is particularly painful when animating the element.

NOTES:
Load the provided reduced test case URL to see the problem.

- On top, see the 30deg rotated element. Notice that it appears to have a thin purple &quot;border&quot;.
- On bottom, the same element without rotation. Note that there is no &quot;border&quot; or bounding box.</thetext>
