Having a go figure with x-axis of type DateTime, the snippet
fig.add_hline(y=10, row=3, col=‘all’, annotation_text=’…’, annotation_font_color=“red”)
changes the range of the x-axis to start with 1970/1/1 which is obviously wrong. This happens in Dash, but not in a Jupyter Notebook. Is this a known bug, or what else?
