my environment

Python 3.11.11
plotly==6.0.0

I have implemented the button and layout as follows:

button = dict(
  label = button_name, method="update",
  args=[
      {"visible": visible_status},
      {"title": button_name}
      ]
  )

def layout(self):
    return go.Layout(
        title=dict(text="title"),
        updatemenus=self._updatemenus(),
        barmode="overlay",
        hovermode="x"
        )

In Plotly==6.0.0, the title set in the layout is displayed initially, but no title is displayed when you press the button.
Using Plotly==5.9.0 the title updates every time I toggle the button.

I thought this might be a problem, so I created an issue.

I'll be using Plotly==5.9.0 for a while.
best regards.
