Thanks. Code looks good. To also remove the results page corner-doodle, add this line to your uBlock Origin "My Filters" block-list...

In my case there is no .BA0A6c used in the html code, but targeting .logo.doodle works.

Thanks for the suggestion of the global ".logo.doodle", Achernar. Could be I was getting Opera-specific IDs in the page code, when I targeted .BA0A6c ?

Could be.
