(Firefox :: Theme, defect)

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:55.0) Gecko/20100101 Firefox/55.0
Build ID: 20170531030204

Steps to reproduce:

Open a website with a dark (transparent) favicon on Windows 10 and switch to another tab. 


Actual results:

Dark favicons are barely visible in inactive tabs. With transparency there are white outlines. 


Expected results:

The icons gets displayed in a clearly visible way and transparency doesn't show white outlines.  

I tested this with Chrome, Vivaldi and Edge on a pretty decent IPS monitor. Every browser shows this behavior in one way or another once the tab color gets too dark. On cheap TN panels this will be even worse. 

Can this even be handled by the browser? Or will this be an inherent limitation of the chosen standard color for Photon?
