  REGRESSION (262120 at main): [UI-side compositing] compositing/hidpi-non-simple-compositing-layer-with-fractional-size-and-background.html crashes

Reviewed by Tim Horton.

Convert the assertion added in 262120 at main to some logging, because some
layout tests with many layers hit it due to hitting the timeout in
`RemoteImageBufferProxy::ensureBackendCreated()`.
