/** |

* Server-side half of `src/blocks/atomic-shared/flex-item-filter.js`. |
| 10 |
* |
| 11 |
* That filter registers one extra attribute — `ablocksFlexItem` — on every |
| 12 |
* non-atomic block, so anything dropped into an atomic Flex or Grid container |
| 13 |
* gets a "Flex item" panel. Registered in JS alone it leaves the two block |
| 14 |
* registries disagreeing about what a block's attributes are, and the editor |
| 15 |
* asks the server to render with the JS set: WP_REST_Block_Renderer_Controller |
| 16 |
* validates `attributes` against the PHP-registered schema with |
| 17 |
* `additionalProperties => false`, so one attribute the server has never heard |
| 18 |
* of fails validation and the render returns 400 `rest_invalid_param`. That |
| 19 |
* takes down every block rendered through ServerSideRender — aBlocks' own |
| 20 |
* dynamic blocks and third-party ones alike. |
| 21 |
* |
| 22 |
* Declaring it here rather than in BlockGlobal is deliberate: BlockGlobal feeds |
| 23 |
* the attributes of aBlocks' own blocks (through each block's attributes.php and |
| 24 |
* the block.json built from it), while the editor-side filter reaches every |
| 25 |
* block on the site. `register_block_type_args` is the one seam with the same |
| 26 |
* reach, and it needs no rebuild to take effect on blocks aBlocks does not own. |
