incorrect verified youtube publisher favicons in auto contribute table

[LaurenWags]

Description

Incorrect youtube publisher favicons are displayed in auto contribute table.

Steps to Reproduce

1. Install 0.60.26 and launch with clean profile
2. Enable rewards (I used panel)
3. Visit a verified youtube publisher (such as https://www.youtube.com/channel/UCqluXkpvWxWBz6sI1JPAsaA)
4. I stayed on this page for about 8s.
5. I then clicked on a video.
6. Once video started I clicked on BAT logo. At this point, I encountered For media publishers, (youtube, twitch), sometimes publisher panel will switch back to site name rather than publisher name #3043 as the panel changed from publisher info (showing generic YT icon) to youtube.com (showing empty favicon)
7. Go to view brave://rewards.

Actual result:

Expected result:

Since publisher is verified, I should see their favicon from their channel.
youtube.com should be showing the youtube icon (not empty favicon).

Also, here are how some other sites behave. Looks like regular website favicons (verified/not verified) appear fine. Unverified youtube channels display generic youtube favicon as expected. Youtube site and verified yt channel favicons do not display correctly.

This is 0.60.26:

Looks like Verified twitch publishers are showing their favicon and unverified twitch publishers just show standard twitch icon:
