    [WPE] Flaky crashes in ScrollingTreeFrameScrollingNodeNicosia::repositionScrollingLayers
    https://bugs.webkit.org/show_bug.cgi?id=213228

    Reviewed by Adrian Perez de Castro.

    When the `FrameView` delegates scrolling to a native scroll view,
    we do not create a dedicated graphics layer for scrolled contents.

    In this case, `static_cast<Nicosia::PlatformLayer*>(scrolledContentsLayer())`
    evaluates to `nullptr` and we hit the assertion.
