Whenever I get a new image URL, I see the image completely unscaled at 100% zoom in the chat window.

But when closing the chat and reopening it, suddenly, the images are properly scaled.

This is with Gajim 1.1.1, url_image_preview 2.3.23 and Ubuntu 18.10 but it's also happening with Gajim under Windows 7 and Windows 10.
