Description

Describe the bug

My domain does not have BIMI so it is using the fav icon from my website to display beside the email. The transparent areas on a icon are not showing as transparent. If you look at the attached screen shot you can see the browser shows it as transparent in the dev tools but the web page is showing it with purple showing

To Reproduce

Create a fav icon for a domain and create transparency sections

Expected behavior

Transparent colours should be honoured and displaced as transparent

Actual behavior

The color marked as transparent shows up

Research direction

Reproduce the favicon transparency issue in the webmail interface using an image with transparent areas, then trace where the website favicon is loaded and rendered. Done means transparent pixels remain transparent in the rendered favicon in Firefox, without the underlying color appearing.
