overflow for image
overflow is animated with the values hidden;visible;inherit;auto;scroll
for an animated image element. The animated image references a simple
SVG document containing a blue circle on a white rectangle, which are
both larger than the image element, moving from top left to bottom right
with a repetition. overflow in the referenced document is ignored.
The overflow animation starts at 5s. If it is visible or auto, the white
rectangle and the blue circle are not clipped.
The timing is indicated with a related text bottom left.
