--- Comment #1 from Michael Catanzaro <mcatanzaro at igalia.com> ---
I guess the WaylandCompositor::Surface is already destroyed before the call to flushPendingFrameCallbacks? It's not clear.

The use of auto list = WTFMove(m_*CallbackList) throughout this file is confusing: I guess that swaps the member variable vector with the default-initialized empty vector, so it's probably OK, but maybe too clever.
