Navigation: Loading the fallback creates multiple wp_navigation CPTs

[scruffian]

What problem does this address?

When a navigation block is in a fallback state, it creates a draft wp_navigation CPT, once a user interacts with it. If this draft is not saved then, next time we load the block we load the fallback again, rather than the draft. This can lead to a situation where a user has multiple draft wp_navigation CPTs in their admin.

What is your proposed solution?

When the block is in a fallback state, we should delete draft wp_navigation CPTs, and create a new one with the latest fallback data, to avoid creating multiple useless drafts.

@scruffian Can we close this one out?

[scruffian]

I don't think so no.

We have a few solutions in the works. We should be able to fix it if we can get one to land. For example #48698

[scruffian]

This has been fixed.
