    [GTK][WPE][Skia] Fix assertion when drawing filters with a zero sourceImage in DisplayList mode
    https://bugs.webkit.org/show_bug.cgi?id=281909

    Reviewed by Alejandro G. Castro.

    applyFilteredImageBufferItem() contains a wrong assertion that a
    sourceImageIdentifier must always be present -- however there are
    legitimate use-cases in SVG when a sourceImage is a nullptr - handle that.

    Covered by existings tests, when using multi-threaded CPU rendering.
