When running WebGL in a debug build, both on Wayland and X11, I see the following warning for every frame:
[Child 51205, Main Thread] WARNING: DMABufSurface::FenceWait(): We're missing fence file descriptor!: file [...]/widget/gtk/DMABufSurface.cpp:254

We call into FenceWait() via SharedSurface::WaitForBufferOwnership()
and it's a valid case that the fence was already deleted via
ReleaseTextures(). Thus don't warn here.
While on it, fix a typo.
