Microsoft Edge. Bring back the option to fade inactive apps.

I upvote this. The fading icon serves 2 purposes:
1. It provides reassurance that the sleeping tabs feature is working as intended, without requiring users to determine whether it's actually sleeping manually by going to edge://discards.
2. The difference between greyed-out and normal icons helps users quickly distinguish tabs that have not been visited recently from tabs that have been visited recently. This is useful when a user wants to go back to the recently visited tabs while navigating through many tabs. This change removes a visual cue from the browser interface.

Restore the greyed-out tabs icon appearance for sleeping tabs. Alternatively, provide a setting that allows users to enable or disable this visual indicator according to their preferences.
