User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:125.0) Gecko/20100101 Firefox/125.0

Steps to reproduce:

On a wide color gamut monitor, run a gradient interpolation test such as
http://wpt.live/html/canvas/element/fill-and-stroke-styles/2d.gradient.interpolate.coloralpha.html

Actual results:

Fail.

Expected results:

Pass.

On the same machine and same monitor, Chrome (Canary 124) passes.

On wpt.fyi, the same test passes in Firefox. The WPT infrastructure provides an sRGB display.
