Update Method Example Broken

The updatemenu method update is broken. It only updates the layout attributes. If you use the same code but change the method to restyle, it updates the data attributes as expected, but obviously this won't work if you want to update both data and layout attributes.

Recreate
This is present for both the custom button and custom dropdown examples on the plotly examples page. You can see the problem by interacting with the examples.

Versions
I have this behavior on plotly 5.5. My friend has this problem in version 4.14. The behavior is the same in my versions of Chrome, Firefox, Edge, and VS Code's Jupyter interface.

Edit: I updated the title after getting some more info.

Inizia con gli esempi di pulsanti personalizzati e menu a discesa personalizzati nella documentazione dei menu a discesa di Plotly e riproduci il comportamento usando il metodo update. Confrontalo con restyle e verifica che la correzione completata aggiorni sia gli attributi dei dati sia quelli del layout negli esempi.
