Transparent user avatars non-opaquely overlap in read receipts

[turt2live]

Steps to reproduce

1. Send a message with an opaque avatar
2. Have a non-opaque avatar user read it
3. Observe read receipts from a third account

Outcome

What did you expect?

The transparent avatar should cut into the opaque avatar, not bleed through. I believe this was the case at some point in the past.

What happened instead?

There is a subtle outline on the transparent user's avatar, and the opaque avatar is bleeding through.

That looks like a related but not duplicate issue? This issue is concerned with the few remaining places where transparency exists, while the other issue is concerned with the grey.

[germain-gg]

Yes that is true, but whatever we settle on will apply to both issues. I've also commented on the counterpart to explain that we have to take in consideration the issue here.
I'm not overly inclined to keep the two open as this will split the discussion needlessly.
