Falling block bed doesn't render

Please see Grum's comment on MC-64634.

That is a 5 year old response, and the command Grum was talking about is Falling Sand, and this is Falling Block. If the command changed to allow other/all blocks to have a falling entity version, then this is Not working as intended.

Reopen the ticket please and let the developers decide if now they want to add the missing entity models for those falling blocks or not.

Falling sand was the old entity name, they could be other blocks for ages.

Beds do not use block models, and instead use block entity special rendering, like the other blocks in that ticket, as such this is a duplicate, not just related.

@unknown is right, this is the exact same issue.
