Description of expected behavior and the observed behavior

AutocompleteInput dropdown does not well with Jupyter Dark Theme. Tested using jupyterlab with following setting:

Complete, minimal, self-contained example code that reproduces the issue

import panel as pn

pn.extension()

autocomplete = pn.widgets.AutocompleteInput(
    name='Autocomplete Input', options=['Biology', 'Biochemistry', 'Physics'],
    placeholder='Write something here')

pn.Row(autocomplete, height=100)

Results in the following behaviour. Notice that the dropdown text is hardly readable because the text is white on a white background.
