 The <dfn method for="XRSession">updateRenderState(|newState|)</dfn> method queues an update to the [=active render state=] to be applied on the next frame. Unset fields of the {{XRRenderStateInit}} |newState| passed to this method will not be changed.
 
 When this method is invoked, the user agent MUST run the following steps:
-
   1. Let |session| be the target {{XRSession}}.
   1. If |session|'s [=ended=] value is <code>true</code>, throw an {{InvalidStateError}} and abort these steps.
   1. If |newState|'s {{XRRenderStateInit/baseLayer}} was created with an {{XRSession}} other than |session|, throw an {{InvalidStateError}} and abort these steps.
   1. If |newState|'s {{XRRenderStateInit/inlineVerticalFieldOfView}} is set and |session| is an [=immersive session=], throw an {{InvalidStateError}} and abort these steps.
+  1. If none of |newState|'s {{XRRenderStateInit/depthNear}}, {{XRRenderStateInit/depthFar}}, {{XRRenderStateInit/inlineVerticalFieldOfView}}, {{XRRenderStateInit/baseLayer}}, {{XRRenderStateInit/layers}} are set, abort these steps.
   1. Run [=update the pending layers state=] with |session| and |newState|.
   1. Let |activeState| be |session|'s [=active render state=].
   1. If |session|'s [=pending render state=] is <code>null</code>, set it to a copy of |activeState|.
