capture Snapshot
Returns a document snapshot, including the full DOM tree of the root node (including iframes, template contents, and imported documents) in a flattened array, as well as layout and white-listed computed style information for the nodes. Shadow DOM in the returned DOM tree is flattened.
Note: this function uses an input class, and constructing this class manually may lead to incompatibilities if the class's constructor arguments change in the future. For maximum compatibility, it is advised to use the overload of this function that directly takes the mandatory parameters as arguments, and the optional ones from a configuration lambda.
