Antoine,
These failures are weird.
They happen mostly when
"border-image-source" is set
* from "inherit"
* to something else
and the window.getComputedStyle value returns a surprising "cross-fade()"
For example:
CSS Transitions and CSS Animations
<border-image-source>
from [inherit]
to [url(http://wpt.live/support/orange_color.png)] at (-0.3)
should be [url(http://wpt.live/support/orange_color.png)]
but it returns
cross-fade(
url(http://wpt.live/support/green.png),
url(http://wpt.live/support/orange_color.png),
-0.3
)
Why the cross-fade() ?
This happens only when the starting value is inherit and different from 0
For inherit and 0, it has a different error
expected: url(http://wpt.live/support/orange_color.png)
actual: url(http://wpt.live/support/green.png)
For inherit and 1, they PASS
Web Animations seem to be mostly working apart of a couple of things.
CSS Animations tests
from image to image mostly fail in the intermediate steps (so except for 0 and 1 which is a PASS).

This is because we treat most of the image types in CSS as animatable when they are not. The `cross-fade()` value is a representation of blending two images. The issue is that WebKit feels those specs should be updated to make those properties animatable.
