25.1 - New Tab opens from dasboard when clicking on widget edit icon ??

[rfox]

After update from 24.7.12_4 to 25.1 - I noticed that every time I hit the widget edit/expand button on the dashboard (top right corner) of a widget - I get a new tab in my browser ?? Tested with Chrome & Firefox - is this new?  I don't recall this behavior in 24.7 ?
