Description Frédéric Wang (:fredw) 2018-06-27 06:10:02 PDT

ASSERTION FAILED: length.isCalculated()
../../Source/WebCore/css/CSSComputedStyleDeclaration.cpp(502) : WTF::Ref<WebCore::CSSPrimitiveValue> WebCore::valueForImageSliceSide(const WebCore::Length&)

This is triggered by the following testcase:

more specifically, the tests "CSS div/span definitions (only valid if pre-reqs pass)".

Since it was consistently crashing, I went ahead and skipped this test on debug in https://trac.webkit.org/r233603
