Newest Canary Build - Red Speaker Icon on Tab

It appears the most recent Canary update included a change of colour for the speaker icon that appears on tabs that make a sound (see photo) but I cannot find any way to change it back to white.

It isn't part of a theme feature, as even switching it to a built in theme still has it showing in red. It's a bit of a flaw when it comes to colour matching, as it's difficult to see on a dark theme.

Is there anyway to change it? I switched to Canary because I could switch off the Bing icon top right, so it's frustrating this is happening.
