showframe not working for scattergeo if geo.scope is set

Expect that when showframe=True that there's a border around the map.

# Create a sample dataframe

Workaround:
Get rid of scope='north america', and the frame will appear with and without showframe defined

Beginnen Sie, indem Sie die bereitgestellte Scattergeo-Reproduktion ausführen und die gerenderte Karte mit und ohne auf "north america" gesetztes geo.scope vergleichen. Verfolgen Sie anschließend den Rendering-Pfad des geo-Frames in plotly.js und überprüfen Sie, dass showframe=True bei konfiguriertem Scope den erwarteten Rand erzeugt und der bestehende Workaround nicht mehr benötigt wird.
