After updating the browser on my Windows 10, the same problem.
Opera is my preferred browser, but it's so annoying that I had to abandon it and move to Chrome.
Developers return everything back!
If I click on the icon in the browser in a virtual desktop, I expect that there will be a new clean browser window, but instead it opens a new tab on another virtual desktop!!! What?
Virtual desktops are needed to share the work on the problem, as I want on each virtual desktop its own set of links have been opened in the browser.
