Details

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:121.0) Gecko/20100101 Firefox/121.0

Steps to reproduce:

I opened MDN Page for Canvas - createConicGradient: https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/createConicGradient

Actual results:

The demo rectangle in the example looks terrible. Colors are washed out. And if I recreate the example in a local page, I find that the fill is half transparent

Expected results:

Bright colors, no transparence. Open the page with Chrome and compare
