🤔 Expected Behavior

The links should open in a new tab when the user clicks on them with the middle mouse button.

😯 Current Behavior

Nothing happens.

🔦 Context

This bug could have been introduced in #5081 but I'm not sure if this has even worked before this commit.

🌍 Your Environment

• Browser latest Firefox, Chrome and Edge
• latest dev-v5 branch

Also does not work in the web components. See: microsoft/fluentui#36567

Since we overwrite the method anyways there might be a fix needed from us as well.

Is it an official standard?

Not really.
It is more of a browser convention / de facto standard that has been adopted for many years by all major browsers.

Opening a link in a new tab using middle-click, Ctrl+Click, Cmd+Click, or the browser context menu is a long-established browser convention supported by Chrome, Edge, Firefox, Safari, and most modern browsers. While not mandated by a W3C specification, users generally expect these interactions to work on navigable links, making support for them a de facto web usability standard.
