App extension links in product action menu now opening in new tab AND original tab?!

[Tristan3dt]

I've got a private app that adds some menu items to the Product 'more actions' menu.

Suddenly I'm seeing that clicking on one of these items does both of these things:-

1. Opens a new browser tab to the target link

2. Also changes the original browser tab to point to the target link

As far as I know, nothing has changed on the code side to cause this.

Searching in the forums reveals similar strange changes in the past, eg: https://community.shopify.com/c/shopify-apps/my-app-open-in-new-tab/m-p/1935658#M59609

It only seems to happen with my own app and not any of the third-party app links that are installed, which is weird.

Is this a glitch?  What can be done to fix it, or to choose what behaviour happens when a link is clicked?

This is still happening.  Its kind of annoying.  Anyone got any insight?
