WebGL resources are not shared between contexts/canvases, so you will need to upload the resources to both of the contexts. There is a draft WebGL extension at https://www.khronos.org/registry/webgl/extensions/WEBGL_shared_resources/ which aims to achieve this, but that has not yet been promoted to approved status. You could try pinging in public webgl mailing list about what the status of its development is. (drafts sometimes are quite rough proposals and not intended to be finalized as-is, not sure if that's the case here)
