Subject: [PATCH] FIX: Defer removing the splash screen until the window load
 event fires (#17225)

There's an obscure bug where really slow devices end up removing the splash screen before they're finished parsing all of the Discourse assets.

This PR won't impact fast devices but should hopefully prevent the premature removal of the splash on super slow devices.
