Bug 106959 – Reflections should force transform-style to be flat

• Status: NEW
• Component: CSS

[Simon Fraser (smfr)]

Reflections, like opacity and filters, should force transform-style to be flat. It would go here in StyleResolver::adjustRenderStyle():

    // FIXME: when dropping the -webkit prefix on transform-style, we should also have opacity < 1 cause flattening.
    if (style->preserves3D() && (style->overflowX() != OVISIBLE
        || style->overflowY() != OVISIBLE
        || style->hasFilter()))
        style->setTransformStyle3D(TransformStyle3DFlat);
