Thank you for the comment, and agree with you, so I rewrote the
function `eww-open-in-new-buffer' with "C-u" support (also with an
optional argument "url"), then there is no "background" description.

I also tested the new patch with tab-bar-mode on and off, it works for
both scenarios.

Please help review again. Thanks.

Best regards
Lin
