Description

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.

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.
