1840497 - Fuzzy failure in WPT css/css-transforms/transform3d-preserve3d-001.html

Status: RESOLVED FIXED

(Core :: Layout, task)

Description

[Daniel Holbert [:dholbert] (PTO until 2/24)]

We have an interop-2023-relevant WPT failure in this test:
https://wpt.fyi/results/css/css-transforms/transform3d-preserve3d-001.html

The failure screenshot shows a fuzzy-failure, with:

maxDifference: 4
totalPixels: 180 

along the edges of some flipped-upside-down text.

We should just add a fuzzy allowance in the test.

We actually have a failure annotation in-tree in our .ini file, here:

Yap, so perhaps just increase the fuzzy tolerance in the test file (e.g. use maxDifference=198;totalPixels=308).

Attachment: Bug 1840497 - Use Ahem and replace Test Text with XXpp so we can detect the rotation.

So it can pass in wpt.fyi (for interop 2023).
