Allow Custom Entities to Use EntityProvider

[spencerfinnell]

Is your feature request related to a problem? Please describe.

core-data only creates context for default entities: https://github.com/WordPress/gutenberg/blob/master/packages/core-data/src/entity-provider.js#L20-L26

However, custom entities can be added with the addEntities action. These entities then not seen as valid by useEntityProp().

Describe the solution you'd like
Instead of pulling from a static list of entities, all registered entities should be given context.

Describe alternatives you've considered
Currently I have duplicated entity-provider.js and reference the local provider vs. Gutenberg's when using a custom entity.

The solution @yoscbd provided above does work, and I have implemented my own custom entities as well. Therefore, I am going to close this out.

Thank you for the link, however the solution linked does not address my original report (and I mention the ability to register entities with addEntities).

Yes, you can register custom entities for use by some hooks/functions, but not all.

My original issue is support for useEntityProp/EntityProvider which does not work with the technique provided above because entity context is only created for locally imported entities, not all registered entities:

Line 28 in 2e40379

...rootEntitiesConfig.reduce( ( acc, loader ) => {

@ndiego is it possible to reopen this so it remains visible? The original report is still a reproducible issue and blocker for things like #43751 (comment)

Yes, absolutely!
