Test that checks that the block object also works or something different? |
What you already did 😄, thanks! |
|
Added label "needs-dev-note' to flag this for WordPress 6.1 release documentation. @Mamaduka it does seem to just need a mention in the "But there is more" section of the Field Guide, rather than a section in a miscellaneous Dev note post? What do you think? |
|
This doesn't need a dev note. There a no plugins affected by it, and the updated argument types are documented in the handbook. |
|
Please don't remove label before the release or at all. Just add a comment why it doesn't need it. If ut' not listed on the tracking issue add the PR number to the comment on the tracking issue |

getBlockTransformItemsselectorblocksarguments. Now it allows passing a single object or array of objects. This matches howgetBlocksByClientIdworks.Why?
When trying to get a transformation for a single block, we often have to pass blocks argument like this -
[ getBlock( clientId ) ]. If arguments aren't referentially equal, thecreateSelectorreturns the new value and re-rerenders the component. This can affect performance if left unchecked.Discovered while working on #40696.
How?
The blocks argument now is cast into an array inside the selector.
Testing Instructions
Tests should be passing.
