Via bug 92569, I'm going to be adding: // FIXME: This could be improved to do a check hasVisibleNonCompositingDescendantLayers(). if ((flags & ExcludeHiddenDescendants) && layer != ancestorLayer && !layer->hasVisibleContent() && !layer->hasVisibleDescendant()) return IntRect(); The !layer->hasVisibleDescendant() check could be improved to know wether those visible descendants are separately composited (the kind of check that hasVisibleNonCompositingDescendantLayers() does).

We still have this FIXME but using attached testcase, I see Safari Technology Preview 164 render it similar to Chrome Canary 112. Just wanted to update. Thanks!
