When I am in the Webflow Editor (not Designer) and click on a link to an external source, multiple tabs with that link open. Sometimes 3 tabs, sometimes 5 tabs at random. This also happens when my client clicks a link.
This is happening with our sites as well. To narrow it down it happens when using an external link being pulled in from a collection and clicking on the link while using the Editor. Also, if you are using a browser that has a heavy pop-up-blocker, it shows up as four links being blocked.
The problem isn’t in the designer mode, it is while using the editor mode.
If I keep the console open, I can actually see a common theme of 4 duplicate pages being stopped when navigating around in designer mode.
