Research direction
Start by inspecting DockerImage.java at line 57, then trace how ContainerRegistryDockerfileActionsProvider and DockerRunLineMarkerProvider construct the image from a Dockerfile. Reproduce the IntelliJ error on the reported environment and verify that the Dockerfile action path no longer produces an uncaught NullPointerException when the VirtualFile parent is absent.
