G3DWarehouseBrowser shows no content because 3dwarehouse.sketchup.com does not support Internet Explorer anymore

G3DWarehouseBrowser opens 3dwarehouse.sketchup.com in CLSID_WebBrowser/IID_IWebBrowser2 based browser. In my case, it is Internet Explorer, which is no longer supported by 3dwarehouse.sketchup.com, so there are no models, it just asks me to upgrade browser.

Is Internet Explorer expected here or am I doing something wrong and others see Edge?

Start by locating G3DWarehouseBrowser and its use of CLSID_WebBrowser/IID_IWebBrowser2. Confirm which embedded browser OpenCOLLADA launches and check whether the project documents an alternative browser integration. Done means the warehouse page can display models in a supported browser, with the expected behavior covered by a reproducible test or documented limitation.
