Recently I started having an issue in which links that I click on on some web pages would not open in a new Tab like normal. After trying all the regular stuff - clearing history and cookies, quitting Safari and reopening, etc., I was still having the issue. I ended up calling Apple Support but they could not solve it either. However, I did some experimenting and discovered that the issue only seems to happen if/ when I have the page as part of a "Tab Group" (new feature in Safari 15). If I have the web site open as a regular tab and not part of a group, everything works fine, but if the page is part of a Tab Group, when I click a link, I get a new tab, but it defaults to my start page. Here's a short video demonstrating the issue. I'm wondering if anyone else is having this issue? If so, it's an obvious bug.
