Bug 263699 – getComputedStyle does not return correct transform

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Ahmad Saleem]

Hi Team,

While going through Blink's commit, I came across another failing test case:

Test Case: https://jsfiddle.net/5oomd14v/

^ Chrome Canary 120 and Firefox Nightly 121 shows:

matrix3d(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 1, 1)
matrix3d(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 1, 1)

While Safari Technology Preview 181 shows:

matrix3d(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 1, 1)
none

Blink Commit: https://src.chromium.org/viewvc/blink?view=revision&revision=201174

WebKit Source: https://searchfox.org/wubkat/source/Source/WebCore/css/ComputedStyleExtractor.cpp#857

In `computedTransform` function and in below:

if (!style.hasTransform() || is<RenderInline>(renderer))

to

if (!style.hasTransform() || !renderer)

leads to passing above but failures in WPT test cases. I haven't explored further but just wanted to raise.

Thanks!
