Crash on a GitHub page with PNG image

[pauloxnet]

I'm using SharePreview 0.4.0 installed with flatpak on Ubuntu 23.10

It works pretty well but fail with the URL: https://pescara.python.it/

The landing page is hosted as a static HTML file on GitHub page, and contains PNG image.

$ RUST_BACKTRACE=full flatpak run com.rafaelmardojai.SharePreview

(share-preview:2): Gtk-WARNING **: 08:07:20.689: GtkText - did not receive a focus-out event.
If you handle this event, you must return
GDK_EVENT_PROPAGATE so the default handler
gets the event as well

The issue was triggered by the data URL of the website icon (data:image/svg+xml,...), added support for those in the app.
