Why is Chrome/Chromium missing the Downloads Icon?

I've had this issue with Chrome and Chromium for some time, thinking it was due to the fact that iconset I'm using is missing some Icons , but I've tried with many different sets and apparently none have the the correct Icon.

Is it Chrome/Chromium that is expecting another icon? (and what would it's name be?) or the sets i have just don't have that Icon?.

I had the same issue.

Solved it by installing the "gnome-icon-theme-full" package.

The Missing icons happen because Chrome/Chromium use PNG files for the MIMES. This range from 16px to 32px. The icons set in use has to have them else it won't display anything like in the screenshot.

Chrome/Chromium don't work with SVG files for the MIMES but can load SVG files for the rest of the UI components.
