Blocks: Support reusable nested blocks (reusable blocks refactor) (#5228
Browse files Browse the repository at this point in the history 
)

* Blocks: Avoid dismissing editable controls

In nested context, block selection changes from reusable block to the inner block being edited, but we want to keep the UI shown

* Block: Move block context provides into BlockEdit

* Revert "Blocks: Disable Convert to Reusable for nested blocks"

This reverts commit 8872058.

* State: Enhance history reducer utils to support ignores

* Block List: Hide disabled default block appender

e.g. within Disabled component, e.g. within reusable nested block

* State: Update reusable blocks as pointers to state blocks

* Block List: Inject inner block list creator as function

Generate BlockList from block's own utils, which has advantage of:

- Not having circular dependency from blocks to editor
- Respecting block menu and contextual toolbar props

* Typo: saved -> fetched

* Typo: preferencially -> preferentially

* Explain why dispatching RECEIVE_BLOCKS is necessary

* Remove unnecessary getState variable

* Update getInserterItems to respect new reusable block data layout

Makes `getInserterItems` and `getFrecentInserterItems` respect that
reusable blocks now point to a block that is elsewhere in the editor
state. This makes reusable blocks again appear in the inserter.

* Provide createInnerBlockList context in BlockPreview

Allow reusable nested blocks to be previewed in the inserter by having
BlockPreview inject a createInnerBlockList function via context.

* Fix flash of 'Not found' error message when fetching a reusable block

Re-order the FETCH_REUSABLE_BLOCKS effect so that the reusable block is
added to the store before it is marked as no longer being fetched. This
prevents core/block from briefly flashing the 'Not found' error message
in between dispatches.

* When converting reusable -> regular, replace the block with a copy

Making a copy of the referenced block prevents the regular block from
being removed should the reuasble block be later deleted.

* Avoid iterating through reusable blocks twice

Use _.map to avoid iterating through the reusable blocks twice in
`getReusableBlocks`.

* Move createInnerBlockList into `editor/utils`
