I found a little bug in brave tabs on android. When I use google search, sometimes favicon is wrong and belongs to other site that I visted previously. I noticed it only on google sites so maybe its the problem from their site but anyway I wanted to post It here to be sure. Here is a screenshot.
As you can see I have a tab on google site but there is a favicon from nexus mods site.
