Drogon burns the Iron Throne

In S08E06, we saw how Daenerys died at the hands of her lover, right in front of the throne she desperately wanted. When Drogon, her dragon and child, found her dead, the viewers expected him to burn Jon for killing her. Instead, after a fit of heartwretching screams, the dragon spewed fire and melted everything in front of him, including the Iron Throne. Could it be Drogon wanting to destroy what led to his mother's demise, at the same time fulfilling his mother's goal of “breaking the wheel”?
