[Steam] In-game News opens in Windows Default Browser, not in Steam Overlay's Web Browser

[R4dioS1lence]

Just had to reinstall Windows after a hardware change, and I migrated all my settings to the new installation.

However, now the in-game news is opening on my Windows default web browser, instead of opening on the Steam Web Browser (the default behavior before).

I checked Steam configuration, and found no configuration to enable/disable opening in-game links on the Steam Web Browser.

I checked Warframe Settings (which were backed up and restored after re-install), and didn't found anything about it.
