The preview that shows when you hover reusable blocks in the inserter has regressed. It shows:

I tried debugging quickly. I think the issue comes from the fact that we use an embedded editor (separate blocks store) but we don't load the content of the reusable blocks in the sub reducer.

Potential solutions

• Refactor the reusable blocks to use an embedded editor (There's some PRs in progress)
• try to load the reusable blocks in the BlockEditorProvider used for the preview.

Questions

This used to work, so I'm curious when it regressed and what's the "hack" that allowed it to work previously.
