Describe the bug

I can change the maxHeight of the dcc.Dropdown component, but as soon as a DataTable loads (even with no styling) the background of the dropdown shrinks back to 200px and any text below that is left, with a transparent background. If I return a boring Div instead of a DataTable, the dropdown stays styled correctly. Seems to be css-related, because the "incorrect styling" sticks around until I close/reopen the tab, then it's good again until a DataTable loads.

Screenshots

If applicable, add screenshots or screen recording to help explain your problem.

Dropdown creation:
dropdown = dcc.Dropdown(options=options, placeholder='Sport', id="sport-dropdown", searchable=False, maxHeight=400, )
DataTable creation

df = pd.read_csv('https://raw.githubusercontent.com/plotly/datasets/master/solar.csv')
return dash_table.DataTable(df.to_dict('records'), [{"name": i, "id": i} for i in df.columns])

This is not unique to DataTable.

If you have a look at the Dash example: https://dash.plotly.com/dash-core-components/dropdown you can see that "Rome" has a transparent background.

This error is caused by a special CSS class used for documentation.
A fix is currently under development and will be available soon
