Please describe your issue in as much detail as possible:

Calling SteamFriends()->ActivateGameOverlayToWebPage("<valid URL>") via the Steamworks C++ API before this update,
The URL would open in the internal browser in the overlay. But... after the new version of the steam client (the "big revamp" release) the URL is opened in the Steam client itself, passing EActivateGameOverlayToWebPageMode::k_EActivateGameOverlayToWebPageMode_Modal doesn't have any effect on the result either. I guess this is a regression.

Steps for reproducing this issue:

1. Call SteamFriends()->ActivateGameOverlayToWebPage("https://google.com/"); in a C++ client linking against the steamapi (tested with v1.57)
2. Observe how the URL is opened in the Steam Client and not the embedded overlay browser.
