If UpdateLifecyclePhasesInternal is called with a target_state of kCompositingInputsClean, we early-exit after the call to UpdateIfNeededRecursive:

...

      if (!RuntimeEnabledFeatures::slimmingPaintV2Enabled()) {
        view.Compositor()->UpdateIfNeededRecursive(target_state);
      } else {
        ForAllNonThrottledFrameViews([](FrameView& frame_view) {
          frame_view.GetLayoutView()->Layer()->UpdateDescendantDependentFlags();
          frame_view.GetLayoutView()->CommitPendingSelection();
        });
      }

      if (target_state == DocumentLifecycle::kCompositingInputsClean) {
        DCHECK_EQ(Lifecycle().GetState(),
                  DocumentLifecycle::kCompositingInputsClean);
        return;
      }

This accidentally skips the following logic at the bottom of this function, which was intended to run for all lifecycles > kLayoutClean:

    ForAllNonThrottledFrameViews([](FrameView& frame_view) {
      frame_view.CheckDoesNotNeedLayout();
      frame_view.allows_layout_invalidation_after_layout_clean_ = true;
    });

This causes us to hit DCHECKs when targeting kCompositingInputsClean.
