It sounds like the root issue is that some people prefer opening new tabs while others prefer staying in the same browser window. I surfed the web when all links, even across websites always stayed in the same browser window, and I still prefer that. But I can understand that some people prefer opening new browser tabs instead.

I think web browsers should revisit how they handle links with target=_blank/_top, and show different cursers when hovering and let users customize the default behavior.

This is not about new tabs. It refers to an in-page panel that displays the content of the linked issue instead of navigating to it.

Idk, it almost seem a workaround for slow/broken go-back? If go-back is fast and state preserving, it's basically a fullscreen modal.

All(?) browser open links in a new tab when middle-clicked?
