replaces the one previously specified. Pass empty array to disable tracking.
Use takeComputedStyleUpdates to retrieve the list of nodes that had properties modified.
The changes to computed style properties are only tracked for nodes pushed to the front-end
by the DOM agent. If no changes to the tracked properties occur after the node has been pushed
to the front-end, no updates will be issued for the node. TrackComputedStyleUpdatesBuilder Builder for TrackComputedStyleUpdates TrackComputedStyleUpdatesForNode Starts tracking the given node for the computed style updates
and whenever the computed style is updated for node, it queues
a computedStyleUpdated event with throttling.
There can only be 1 node tracked for computed style updates
so passing a new node id removes tracking from the previous node.
Pass undefined to disable tracking. TrackComputedStyleUpdatesForNodeBuilder Builder for TrackComputedStyleUpdatesForNode TrackComputedStyleUpdatesForNodeReturnObject Starts tracking the given node for the computed style updates
