Research direction

Reproduce the issue with the shown FigureWidget example, then trace how widget.layout["shapes"] and widget.layout._props["shapes"] are populated after drawing a shape. Compare the public property and internal props behavior, and confirm done when the public shapes property reflects the drawn shape.

Description

bug P2

When using FigureWidget, the shapes property does not update properly.

Here is an example:

fig = go.Figure()
fig.update_layout(
    modebar={"add": ["drawline", "drawclosedpath", "eraseshape"]},
)
widget = go.FigureWidget(fig)
widget.show()

When I draw a shape, widget.layout["shapes"] remains empty. On the other hand, widget.layout._props["shapes"] is populated correctly.

This is using Plotly 6.2.0.
