Description

Not sure if I'm saying this right, but in 6.3.2 this custom taxonomy component for a custom block looked like this:

and in 6.4 it now looks like this:

(I confirmed this by changing nothing in our plugin's code, and only rolled back / forwards the wordpress version.)

This is being looped inside a Repeater field we've made, and the SlotFill implementation is standard as per the docs.

Inside our Taxonomy Settings Panel component:

// ... other stuff
<Fill name={ 'repeaterControls' }>
{ checked && (
	<Button
		isSmall={ true }
		text={ 'Settings' }
		variant={ open ? 'primary' : 'secondary' }
		onClick={ () => toggleOpen( ! open ) }
	/>
) }
</Fill>

Block Edit.js:

<RepeaterFieldV2
  fields={ taxonomies }
  >
  <TaxonomySettingsPanel
	  availableTaxes={ availableTaxes }
  />
</RepeaterFieldV2>

Inside Repeater.js:

<SortableContainer>
{ !! fields && fields.map( ( field, index ) => {
	return (
		<SortableItem
			key={ `item-${ index }` }>
			{ props.children }
		</SortableItem>
	);
},
) }
</SortableContainer>

And inside our Sortable Item:

<SlotFillProvider>			
  { render }
  <div className={ cls.elem( 'controls' ).toString() }>
	  <Slot name={ 'repeaterControls' } />
  </div>
</SlotFillProvider>

Is this a bug? Did something change in the Slotfill package or somewhere else that would explain this change in behaviour? Again, we haven't changed anything at all in our codebase regarding these items between 6.3.2 and 6.4.1, so any help would be appreciated.
