Scattermapbox, Choroplethmapbox- '<br>' tag is not respected on displaying a text

[empet]

I defined a Choroplethmapbox with below=True, hoverinfo='none', and a Scattermapbox
with mode='text, and text of the form:

text = ['Sales<br>17%', 'Sales<br>8%', ...] ,

but a snippet from the resulting image shows a single line text.
