Bug 81029 – css3/filters/custom/custom-filter-property-computed-style.html passes in browser, fails in DRT

• Status: RESOLVED
• Resolution: INVALID
• Component: CSS

[Tim Horton]

Running this test in DRT, I see:

Custom with vertex shader : custom(url(vertex.shader))
FAIL removeBaseURL(filterStyle.getPropertyValue('-webkit-filter')) should be custom(url(vertex.shader) none, 1 1 filter-box). Was none.
FAIL jsWrapperClass(filterRule) should be CSSValueList. Was CSSPrimitiveValue.
FAIL jsWrapperClass(filterRule.__proto__) should be CSSValueListPrototype. Was CSSPrimitiveValuePrototype.
FAIL jsWrapperClass(filterRule.constructor) should be CSSValueListConstructor. Was CSSPrimitiveValueConstructor.
FAIL filterRule.length should be 1 (of type number). Was undefined (of type undefined).
FAIL subRule.operationType should be 12. Threw exception TypeError: 'undefined' is not an object (evaluating 'subRule.operationType')
FAIL removeBaseURL(subRule.cssText) should be custom(url(vertex.shader) none, 1 1 filter-box). Threw exception TypeError: 'undefined' is not an object (evaluating 'subRule.cssText')

etc.

Running this test in Safari, I see:

Custom with vertex shader : custom(url(vertex.shader))
PASS removeBaseURL(filterStyle.getPropertyValue('-webkit-filter')) is 'custom(url(vertex.shader) none, 1 1 filter-box)'
PASS jsWrapperClass(filterRule) is 'CSSValueList'
PASS jsWrapperClass(filterRule.__proto__) is 'CSSValueListPrototype'
PASS jsWrapperClass(filterRule.constructor) is 'CSSValueListConstructor'
PASS filterRule.length is 1
PASS subRule.operationType is WebKitCSSFilterValue.CSS_FILTER_CUSTOM
PASS removeBaseURL(subRule.cssText) is 'custom(url(vertex.shader) none, 1 1 filter-box)'

etc.

patch to land failing expectations

TestFailures suggests it might be flaky; I've never seen it pass.

This either passes under WKTR, or is just flakey:

Passing with WKTR and not DRT would vaguely match the fact that it passes in Safari (with WK2) and not DRT.

Nope, it passes in a WK1 Safari window too.
