Description

Hi All,

I'm attaching one event to the plotly_legendclick, but when I'm clicking in the legend I get an event with the data but the line I've clicked comes with the parameter visible with the previous state instead of the current one.

Reproduce Steps

Codepen: https://codepen.io/fsantiago99/pen/BaxYQJw
Click in BB and toggle it again, the alert is showing the variable visible.

I'm not sure if it is a feature or a bug but please have a look here.

Research direction

Start with the linked CodePen reproduction and inspect the plotly_legendclick event payload while toggling BB twice. Compare the visible value in the event with the legend item's state before and after each click. Done means the event reports the intended current state, with a regression test or other verified reproduction covering the behavior.
