Here's the latest discussion about it on WhatWG: https://github.com/whatwg/html/pull/8213

Here's the relevant spec: https://html.spec.whatwg.org/multipage/canvas.html#dom-context-2d-createconicgradient

And the broken WPT: https://wpt.fyi/results/html/canvas/element/fill-and-stroke-styles?label=master&label=experimental&aligned&view=subtest&q=canvas%20conic

This means that the angle on ConicGradient needs to be +PI/4 to match the rest of the Canvas API.
