Steps to reproduce

Click the 'ToggleShow' button

What is expected?

All nodes should enter slowly

What is actually happening?

Only the first node will behave this way

After clicking twice, the console prints: Cannot set properties of undefined (setting 'disabled')

System Info

Any additional comments?

I have tried making modifications, but I am not sure if they are correct
