On Chrome, middle clicking on an external link opens the page in the current tab after a small delay instead of opening it in a new tab.
To reproduce, go to [this page](A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums) and try to middle click the git-annex link. It will open in the same tab. To see the correct behavior, scroll down and middle click the Tutorials category, it will open in a new tab.
Right clicking and selecting open in new tab works as expected for both types of links.
You might need to take off the / before the parenthesis after you open the link, it seems there’s a Stack Exchange bug with the way the link is formatted
