BLS attestations are sometime tagged as not included in the block

Go to https://nomadic-labs.gitlab.io/teztale-dataviz/Level#server=https%253A%252F%252Fteztale-ghostnet.obs.nomadic-labs.cloud%252F&block=16224899&round=0&summary=attestations&source=sagotch and see the list of Lost attestations. These are delegates with tz4 consensus keys. These attestations are stored in the block aggregated, and Teztale is likely no to be able to handle the aggregated attestation correctly.

Some levels are correctly reported though: https://nomadic-labs.gitlab.io/teztale-dataviz/Level#server=https%253A%252F%252Fteztale-ghostnet.obs.nomadic-labs.cloud%252F&block=16224902&round=0&summary=attestations&source=sagotch
