IRequestHandlerOnOpenUrlFromTab Method
Version 63.0.0
Called on the UI thread before OnBeforeBrowse in certain limited cases where navigating a new or different browser might be desirable. This includes user-initiated navigation that might open in a special way (e.g. links clicked via middle-click or ctrl + left-click) and certain types of cross-origin navigation initiated from the renderer process (e.g. navigating the top-level frame to/from a file URL).
