__experimentalUseHasRecursion deprecation is attempting to spread a non-iterable variable

Description

gutenberg/packages/block-editor/src/components/recursion-provider/index.js

Line 79 in fd060e3

export function useHasRecursion( uniqueId, blockName = '' ) {

__experimentalUseHasRecursion accepted a string argument (above), the deprecation instead tries to spread a props object (below)

gutenberg/packages/block-editor/src/components/recursion-provider/index.js

Line 100 in 49532f3

return useHasRecursion( ...props );

Step-by-step reproduction instructions

make a block that uses __experimentalUseHasRecursion in Wordpress 6.4.3 and in 6.5.

observe that it works with a unique id as the sole argument in 6.4.3, and that it errors in 6.5 with this message in console appearing: TypeError: e is not iterable

Thanks for reporting @albanyacademy. I've put together a fix, which should land in the next minor WordPress release.

no worries, i absolutely wasn't using an experimental feature in a production environment by the way, nope no way just happened to notice it somehow for completely different reasons 😬
