Creating two different scatter_mapbox, one often fails

I create two different scatter_mapbox with similar data.

Sample:

div_mapbox = html.Div([dcc.Graph(figure=figure, id='figmapbox', style={'width': '90vw', 'height': '90vh'})],
                         id = 'divmapbox',
                         style={'width': '90%', 'display': 'inline-block', 'height': '90%', 'position': 'absolute', 'z-index': '1'}
                         )

With figure either:

def get_fig_openseamap(wpts):
    fig = px.scatter_mapbox(data_frame=wpts, lat="lat", lon="lon", size='size_marker', size_max=8, opacity=1.0, hover_data={'size_marker': False, 'lat':False, 'lon': False, 'energy': True, 'dist': True, 'eta': True})
    fig2 = px.line_mapbox(data_frame=wpts, lat="lat", lon="lon")
    fig.add_trace(fig2.data[0])
    fig.update_layout(mapbox_style="open-street-map")
    fig.update_layout(mapbox_layers=[source_openseamap])
    fig.update({'layout':{'autosize':True,
                          'margin': {"t": 5,"b": 5,"l": 5,"r": 5}}})
    return fig

Or:

def get_fig_northstar(wpts):
    fig = px.line_mapbox(data_frame=wpts, lat="lat", lon="lon")
    fig2 = px.scatter_mapbox(data_frame=wpts.query('ghost == 0'), lat="lat", lon="lon", opacity=1, hover_data={'lat': False, 'lon': False, 'energy': True, 'dist': True, 'eta': True})
    fig.add_trace(fig2.data[0])
    fig.update_layout(mapbox_style=mapbox_style_northstar)
    fig.update({'layout':{'autosize':True,
                          'margin': {"t": 5,"b": 5,"l": 5,"r": 5}}})
    return fig

Where openseamap layer is the openseamap marks tile.
Nothstar is the official mapbox style northstar, that needs to be copied into a personal account to work.

I can run each of them on its own, no problems. Sometimes, running both works, and sometimes it fails.
The failure normally appears like one map working perfect, the other has no graphics, BUT the hoverlayer works, so hovering over a point (that cant be seen) shows the hover data.

It seems a bit stochastic to me.
I can also replace the figure with callbacks using Output('figmapbox', 'figure')
As long as it's one at a time, it works fine. Having both can work but normally not.
Any suggestions how to debug this? I have suspected race conditions and tried delaying creating one of them but saw no improvement.
