<title>CSS-UI test: outline-offset width negative values — long box</title>
<meta name=flags content="should">
<meta name=assert content="Negative values on outline-offset should not cause the height and the width of outside of the shape drawn by the outline to become smaller than twice the computed value of the outline-width property, applying this constrain separately for each shape if there are several shapes.">

<style>
span {
outline: solid green 25px;
outline-offset: -35px; /* Any value that makes sure the outlines collide ( < -25px )
would make the test valid,
-35px is just one such value that happens to make the failures pretty.
I recommend looking at this test in as many UAs as possible,
the results are quite astonishing.
