CF8 Repeater Area containing dropdown field

Environment:

• J!5.4.0
• CF:8.0.50
• PHP:8.3.27

I have a simple test form that has a repeater area that contains a dropdown field with a simple static list of options.

I find that if I create initial clone instances via a php action then the dropdown works as expected for those clones, but for any clone added within the form the dropdown does not work.  There are no javascript errors in the console.

This issue occurs for clones created by javascript either from clicking an add clone button or setting "Start Count" >0  in the Repeater Area.
