[Problem]: Impossible to use GetFavicon in synchronous manner

[Curve]

What happened?

The callback provided to GetFavicon is never called when waiting for the result by entering the message-loop.

Example Code:

web_view15->GetFavicon(COREWEBVIEW2_FAVICON_IMAGE_FORMAT_PNG,
                                                       Callback<GetFavicon>(callback).Get());

// Wait for the result and call PeekMessage continuously

Is it possible to somehow get the favicon in a synchronous manner? As we've seen above, entering the message loop does not help - Is there something else we're supposed to do? The callback is triggered when not waiting for the result.

Importance

Moderate. My app's user experience is affected, but still usable.
